Twitter apps and services

Bloggersblog provided a list of Twitter apps most of which are Twitter or Tweet such as:

1. Ego Twitter'in.
2. Qwitter.
3. Tweet Scan.
4. Tweetburner.
5. TweetClouds.
6. Tweetgift.

And of course the list goes on.  Not being a Tweetgeek I haven't got round to checking them all but surely it is only a matter of time before we have Jobtweet, Twitjobs or whatever name someone can think of.  It seems as far as Twitter apps are concerned, the silliest names get chosen so maybe the suggestions above are in with a great chance!
