Last week, Twitter started testing out a “Who to follow” feature. Basically, it’s a recommendation engine for who you should follow, similar to ones that Facebook and others use. At the time, I noted it was a good idea and should bulk up their social graph. But today I actually got the feature activated on my account — I believe I vastly understated what this feature could mean.
The main way most users will interact with this new feature is in the sidebar. There, right below your tweet stats, you’ll see the two users that Twitter is suggesting that you might like to follow. How do they determine this? If you click the “view all” link (or go to the Find People area) you’ll notice this is all based on the people you’re already connected and who they follow. Again, this is like the feature Facebook has.
