Tweetag a new way to search Twitter.

There’s a new way to search Twitter. Techcrunch says of Tweetag:

“The app, like most Twitter-related applications, is fairly simple: you enter a tag, and Tweetag will show any public Twitter messages that contain that particular keyword, but more interestingly also a list of other tags that are related to it.”

Then of course there is Tweetscan who also keeps a database of historical ‘Tweets’ which you can download and search to your hearts content.
