VisibleTweets is a neat visualization app that searches Twitter for keywords.   The tag cloud setting is useful as it creates a tag cloud of related terms.  I did a search for “job san francisco” on the tag cloud visualization mode and it pulled up a series of useful tweets and created a succession of clickable tag clouds of keywords it finds that are related to the original search.

I wouldn’t describe VisibleTweets as the world’s most useful business Twitter application. That said, it does come in handy for me at least when researching a variety of keywords and activity around topics that are in use on Twitter.

For all unicorn and rainbow fans, it rotates through a very nice color palette.  Note the lovely shade of purple below.
