ErlPort - Erlang port protocol for Python. A somewhat different approach to distributed communication is this module, which simply implements Erlang's built-in communication tools (ports and terms). With this, you can build systems that use Python or Erlang as the implementation language, depending on your needs.

Distribunomicon | Learn You Some Erlang for Great Good!. Interesting article about distributed processing with Erlang and the pitfalls you can fall into (e.g. the note that remote links can produce an event storm if the network fails over which the remote links go).
josevalim/elixir is a programming language for the Erlang environment and its virtual machine, which integrates into the Erlang environment and has a similar focus as Erlang. However, Elixir provides a Ruby-like syntax and some interesting extensions as well as, of course, interoperability with Erlang code (otherwise it wouldn't make sense, because Erlang is not just the rather strange language, but above all the server structure and the libraries).
Zotonic - Hmm, should I take a look at this? A CMS in Erlang that has some interesting features on the list - and aims a bit in the direction that Drupal also has, i.e. rather a CMS construction kit than a pure pre-made blogging solution. The admin interface also looks quite tidy.
"When you choose an eventually consistent data store you're prioritizing availability and partition tolerance over consistency, but this doesn't mean your application has to be inconsistent. What it does mean is that you have to move your conflict resolution from writes to reads." via Mochi Labs - statebox, an eventually consistent data model for Erlang (and Riak). Also interesting outside of Erlang, as the problem is of a more general nature - data models for transactional databases cannot simply be transferred to an eventually consistent database like Riak (or Cassandra). The reason lies in the fact that conflicts only become apparent later when reading, as they are still "on the way" beforehand.
Using Erlang to Build Reliable, Fault Tolerant, Scalable Systems | October 12, 2009 - interesting case study on using Erlang for fault-tolerant systems.
Chicago Boss - the no-nonsense MVC framework for Erlang - no idea what will come of it, but the beginning already looks quite interesting.
lionet: Erlang, Yaws, and the deadly Tornado - very interesting comparison, as Erlang is often presented as scalable, but it is not often examined as a whole. Yucan and Misultin mentioned later in the article sound very interesting for some purposes, as scalability through the Erlang runtime becomes even easier - and process communication is simply easier to implement than with isolated Python processes. On the other hand, Python is a known quantity for me, so Tornado will certainly find its way into my toolbox.
Geeking out with Lisp Flavoured Erlang - I really need to finally deal with Lisp Flavoured Erlang.
Somethings to rejoice about - about the changes in Erlang 13A. Especially very nice: finally real Unicode support in Erlang.
CouchDB Implementation - those who want to know how CouchDB stores documents, how all access paths are structured, and what technology is behind it, can read the article here.
Disco - Map/Reduce with server in Erlang and API in Python.
Rabbiter - interesting project based on RabbitMQ that could provide the basis for Twitter services. Everything in Erlang and massively designed for scalability.
Erlang GS Explorations - Organized by Doug Edmunds - interesting collection of graphics functions from Erlang.
Yhc/Erlang/Proof of concept - interesting project that translates Haskell to Erlang bytecode (BEAM) and thus enables mixing of Haskell and Erlang code.
Erlware - the start of a package repository for Erlang. Could be very interesting - I know it from Perl's CPAN and Python's cheeseshop, both of which provide a lot of relief when using available modules.
Tenerife Skunkworks: Parsing text and binary files with Erlang - nice article about one of the mysteries in Erlang: how to handle strings? Lists of characters or binaries? (oh, and everything I've written in the last few days is gone due to a server crash. Hmm. Did I have anything interesting to say?)
Hello, Bob. Hello Joe. - Bob Ippolito on Erlang development and his (good) experiences.
External Filters from Erlang - interesting post about managing a pool of external programs from Erlang and assigning tasks to them. All in OTP technology.
RE: question about Erlang's future - Erlang's status at Ericsson today (not as positive as one would wish, but an explanation for Bluetail and e.g. their SMTP server in Erlang).
Programming Experiments: Initial Release of my web tools - two small libraries, especially Weberl is interesting as it is based on OTP for configuration and structure and works with classic Erlang Behaviours. OTP thus offers very simple scaling to multiple web hosts.
The Red Hot Erlang Blog - interesting blog software in Erlang. One should take a look at it, some of the features look nice.
Erlang For The Practical Man - quick and dirty tutorial for a practical application (convert a POP3 mailbox to an RSS feed).
Haskell vs. Erlang in a sample project - detailed post about Haskell and Erlang in a project with quite specific requirements (binary protocol, a lot of threads). Interesting insights into the strengths of Erlang.
Vendetta Online - digging through their news there and finding out that their server side is created in Lisp and Erlang. Originally Lisp, which is slowly being migrated to Erlang (due to Erlang's suitability for parallel and distributed systems). Cool. And there's a Mac OS X version of their game client too!
tercio - webapp framework for Erlang with a focus on the specialties of Erlang/OTP.
ETOS Compiler - compiles Erlang source to Scheme (Gambit-C).
Erlang Cookbook - another cookbook site for Erlang. Nice for first impressions of the language.
PragDave: Adding Concurrency to Our Erlang Program - second round. Not really practical code - the application can overload the Amazon Webservice and block your own key - but nice as a demo of how to convert sequential code into parallel. Where the hint about pmap as an alternative is not entirely unimportant ...
(The Scheme Way): Erlang or Gambit-C/Termite? A practitioner's perspective - Erlang wins the comparison. Some good points - especially Erlang's infrastructure is simply better and more mature.
Wings3D - is written in Erlang. Here is the evidence as a link to the source repository. I didn't know that before - a 3D modeler, written in a functional language.
PragDave: A First Erlang Program - Accessing Amazon Webservices with Erlang. Basic tutorial, expects nothing complex.
Serval - VLAN software switch in Erlang. Fun idea - implement VLANs over IP tunnel (basically VPNs). Virtual patch cables, virtual MAC addresses, virtual switch ...
Tsung - Load-Tester in Erlang. Can test various protocols (including SOAP web services and HTTP servers).
What is Eddie? - Load balancer on both DNS and HTTP level, written in Erlang. Website is a bit marketing-heavy, but a very interesting project.
Comprehensive Erlang Archive Network - a brilliant way to install Erlang - a self-extracting shell archive for various platforms and a good package library to quickly install additional packages. Great for trying out.
Inets 2.5.5 - Webserver in Erlang
Yaws - another web server in Erlang - this one is HTTP 1.1 compatible and contains approaches for web development
