I`ll make it short and sweet: I would find it super useful, if usernames that get mentioned in a comment or post would automatically become a link to the userprofile when prefixed with an "@".

So just like it works on Twitter, @maatc would be magically turned into @maatc

Bonus: Getting a notification when someone mentions you
(or a link on the site that functions as a search for recent mentions)

@lucky760 @dag @campionidelmondo @siftbot What do you think? Useful? Possible?

Everyone elses feedback is welcome too of course!
