I agree that Twitter can often be frustrating and time wasting. I hate having to search through people's Tweets to catch the start of a conversation. But in a way it's strangely fascinating, like maybe you shouldn't be reading it...

I do like Friendfeed a lot but find it almost impossible to get my local active group of Twitter people to use it. I post stuff on there and it just goes into a void. No-one follows you on Friendfeed (except yourself, maybe Scoble) and it feels a bit one sided. I want to use it more though so I'm not going to give up.It will catch on more in Europe but it's going to take time.
