So color me unimpressed with Twitter. I believe their functionality has changed, because there is no way that in their current state they would get more than 8 users, and those users would only be involved because their masochists.
It's a great idea, and kind of fun, but holy cow their web site has problems. Maybe it's me, but I don't think so.
First of all, there is currently no way to search for other users using twitter. So I found out that I have two friends using twitter, but guess what? Can't do anything about that. The only way to search Twitter is to use a third party program. The problem? That third party program doesn't have access to let you add them as a friend. So you can see them, but you can't actually add them to your list.
The only way I can see that you can add a friend is if you happen to be on the web site when they add something. There is a 'public timeline' that shows EVERYBODY who is twittering. So if you call your friend, tell them to twitt, and the hit refresh until you see their message, you can then and only then, add them as a friend.
I've checked the FAQ and the help and it's useless. They point you to the third party API that again, doesn't allow you to add them. I submitted an e-mail to their help, but it froze up their server. When I tried to go back I got an error message.
Anyway, as I mentioned, I'm not impressed. I hope they turn their user search back on, because I can see how this would be a fun little app.
