Here's a little bit of history with me and the project :)
I found esoTalk in January 2009 through a post on the ubuntu forums created by Toby. I started out mostly testing it and reporting bugs. Next I began working on a few plugins. I liked the clean design and fresh approach, breaking away from traditional topic/thread model seen in most forum software. Here's the esoTalk I originally started with https://vimeo.com/2867330
At one point I started a web service myesotalk (dot) com and created a system to allow free esoTalk hosting. I was using a custom written management system and modified esoTalk installation to host multi-site installs similar to Drupal or Wordpress. It actually worked pretty well, though it was probably very hacky code :) it was never open to the public. Due to esoTalk being rewritten at the time, I stopped working on the free hosting solution, and have since let the domain expire.
In 2011 I did a presentation/demo of esoTalk to the linux users group at my school. Here's a link to that presentation .
So I was a "developer" of esoTalk but mostly bug fixes or testing, not as much feature work. I've always been a fan of the software because it was a different approach to forums, and the community around it has been great. I haven't been as involved the last few years being away at school and whatnot, but I'm planning on continuing community support of esoTalk and supporting Flarum when that's released.
I should also note that I don't really have a website to use a forum on anymore... but I still enjoy helping out where I can so others with communities can use great software.
