Seesmic is … ok. I doubt i would ever use it, mainly because i have no interest in any of the people posting on it. Also, the fact that you can’t search for videos/keywords that might interest you, makes it virtually pointless. Unless you have nothing better to do and have time to browse through hundreds of random clips. It would be better if it had a search bar.
I like that it’s an interesting way of communicating, like twitter or facebook but with videos, however it takes so long to do and load and is generally too much of an effort. It would be better if it was linked to facebook so that you’re posting videos to people who actually know you and are interested in what you’re talking about. Also, it would probably be easier to find videos that you’re interested in.
