Did you ever want to ask your colleague about some particular line of code? With SourceTalk you can do it in a more convenient way. SourceTalk is an online code discussion tool supporting integration with Sublime Text 2 (via plugin).
Currently the plugin can only start a conference with your current source file in a browser, but we are planning to do a deeper integration that will allow you to discuss code directly from your editor.

Download plugin: http://sourcetalk.net/downloads/sourcetalk.sublime-package (we'll also push it to Package Manager channel shortly).
P.S.: We really need your feedback. If you want an improved version of the plugin to be released shortly, let us know - the more motivative feedbacks we have, the harder we'll work to release a new version.
