Yes, Twitter and Facebook allow people to talk to their favorite celebrities directly, but as far as asking questions and getting answers, formspring.me takes the cake.
It has come under some fire because people abuse it by making offensive comments anonymously. In this situation it’s pretty simple—either ignore them, because they aren’t worth your time, or switch to only accept questions from registered users.
It’s like a press conference and everyone is invited. It is an awesome opportunity for athletes to talk to their fans—regardless of their age. It could make quite an impact on a kid to get a direct answer from one of his favorite stars.
Wikipedia’s founder Jimmy Wales has quite a few interviews online that I watched for a speech I gave about a year ago. Many of them repeat the same questions, however, just like most celebrities that go from show to show. That isn’t their fault, they probably get tired of answering the same questions too. But for anybody who has ever wanted more after a two minute television interview, formspring is perfect. Wales did it and had a few hundred questions within a few minutes. It allows you to see people more as human, and less than a talking head on TV. They just need to sign up.
