Thanks for creating twitter and giving that chance to appeal our request to you. I desperately believe that we should able to search people according to our common interests, so it would be much easier to discover new accounts/people which have same interests with us.
For example, If I am interested in rugby, Boston, deadmau5, tennis etc. when I write all of them down, I would like to see which account/user is used either all of them or half of them before or used a lot in past. In that way, users may decrease result’s quantity and increase searching quality. In my opinion, users will be more satisfied by that option.
