I'm sorry if this is not the right place to be asking this. Please move my question, if necessary.
I've been wondering: why is it not possible to follow people? I sometimes find certain people who answer questions of a particular type (usually tag that I follow) to be quite knowledgeable in that field. So... I go and check their answers to other questions they've replied to so I can sometimes learn cool new things. This often helps narrowing the learning curve when learning a new technology you're still a newbie in. So... wouldn't it be way cooler, if, (just like in GitHub), you could simply follow a person (both their questions and answers)...?
