It’s good to see that Twitter is has introduced the new “You
Both Follow” feature, which lets you look at a Twitter user and see whom you
follow in common. My first reaction was “what took so long?” After all, one of
the key inputs to any social system (online or off) is identifying who you have
in common with other participants. Similar features have been available in other
social networks like Facebook and LinkedIn for quite a while.
Since You Both Follow has only been rolled out to 10% of the user base, here's a screen shot of it (courtesy Mashable):
You’re Both Followed By: this is the flipside of You Both
Follow. Who are the people who follow both you and the Twitter user you’re
viewing. This is probably just as important as You Both Follow; when assessing
the credibility of another user, seeing that they are followed by people you
respect makes you more likely to follow them as well.
Are they following me? Today, when I look at a user on Twitter, I can easily see whether I am already following the user. But, there’s no indication of whether they are following me. How many times have you tried to DM someone, only to see that they are not following you? A simple indicator “@graubart is following you” would make life a lot easier.
The ability to mine the social graph is a huge opportunity and there's no reason Twitter shouldn't expose these simple queries.
