If you are a heavy user of Twitter, nothing is worse than trying to find an important link that is buried in your feed. Check out Twitter Archives. If you think the interface to the Google homepage is stark, wait till you take a look at Twitter Archives.
One big problem with the site is that you cannot conduct any type of search. Let’s say that you are really ichin’ to find my post on Legal Problems of Social Networks. You would be SOL. The site simply lists your Tweets page by page, which is still better than the Twitter website.
