Twixperts lets you either ask or become a subject expert, both for free. So we are immediately not sure where the revenue model comes in, if one will exist. But you do sign in with oAuth and away you go.
As a person posing the question you simply enter it and choose a category. Now I did not see anyway to add additional categories, which is nice in one respect. People couldn’t randomly make up categories and have questions flying all over. However, I did not see a way to request or find additional ones either. Once you ask, simply sit back and wait for an expert.
As an expert, you need to follow one of the category “bots” on Twitter to get the questions in your stream. You then reply to the bot and it takes care of the rest. I think. I couldnt find the names of the bots either in the time I was on the site.
One of the problems was the lack of help in the flow of how it all works. They did have a help page, but some more description on how you know one was answered, or even better when it was answered, was not there. So threading and conversation type viewing would be nice. It shows who asked the question, with their avatar, and how long ago. But then nothing more to follow along.
There was some decent questions being asked that I was interested in seeing the answer to. But I could not track that part down. Just the questions themselves.
In all the site UI is clean and pleasing. The flow needs some work. Categories need some expansion and people need to be in there as experts!
