GitHub has just released the ability to @mention other GitHubbers, which will notify them via email (you can turn off notifications if they get annoying). I think this is a great feature but what’s more interesting is the standardization around the @mention model.
As many of you already know, this idea was introduced by Twitter users in 2006, as a way to mention other Twitter users. More and more folks did this and Twitter quickly rolled out support by linking up these @mentions users Twitter profile.
Fast forward to 2011 and this model is being copied by many new startups (including GitHub and Facebook). It’s good for the web industry when these simple user-generated standards become adopted across many apps.
