Definition 6 Client Manager, Andy McCann, on how twitter is replacing search...

Tapping into interesting news and seeing what people (you care about)have to say is one aspect of Twitter but its also becoming more and more of a relevant tool for search.  It's strengths are in local search, news feeds and product and company news.  There is a great article on Media Post that you should take the time to read.  Here are a few key points that I took away from it:

• Twitter reaches a community that is multiple times larger than your contact list in your phone
• Twitter search is real time in reverse chronological order
• Product and company reviews are also a snap to find and address what is happening today, not last month or last year

There is a vast amount of news and information being transmitted through Twitter everyday which can be a good way to learn what users are saying about your own product or service.  Reversly, if you're in the process of a website design or redesign project, Twitter can be a useful viral marketing tool.
