Much has been written and spoken about Twitter recently.  Some people love it, and others view it as a waste of time.  Also, the lack of a business model that produces revenue has been discussed.  Does Twitter act like email, search, and/or social networking?  The answers currently appear to be no, no, and yes.

This week, the people at Hitwise came out with some research on where people are going after visiting Twitter.  Indications are that Twitter is acting more like social networking than search or email.  Two out of five visitors are visiting social networks or entertainment sites after visiting Twitter.

At this point, very little Twitter traffic is visiting retail sites (search activity) nor is the traffic visiting finance, business or dating sites (email activity).  It appears to be more about social networking and distributing content, especially photo-sharing, than on selling products or services.

Things are sure to change rapidly, but it appears that the monetization of Twitter and its growing traffic is a work in progress.  This potentially huge opportunity is still there for the taking.
