Webware’s Rafe Needleman did a great piece titled Grouptivity Trying to Build ‘Digg for E-Mail’, where he talks about how the company is trying to redefine the “Email This” button.

Rafe writes:

Unlike other E-mail This buttons, the Grouptivity tool sends the story to a public repository, a Digg-like site called iPond. On this site, users can see what the most e-mailed items are from all of Grouptivity’s users. iPond also helps a bit with SEO for the sites that use it, since it’s a giant page of links that, hopefully, will get used by a lot of people.

and ends by saying:

Kumar says that the users on the New York Times’ site send 50,000 “E-mail this” articles a day. If that’s accurate, adding some new functionality to this operation makes a lot of sense
