What this means for you, the user, is that you'll now be notified if you're mentioned by another twitter user - whether you follow them or not.
We think that mentions are important and should stand out from the normal 'background noise' of twitter. So we decided to differentiate these tweets by using a new colour scheme. That way they are immediately noticeable; even in a collection of 100s or even 1000s.
We hope you like it.
