"Freemium"

New word...for me, anyway.

Freemium.  First articulated by the venture capitalist Fred Wilson.  Basically, it's the business model of generating traffic and users by offering a free service.  Then, upselling that customer base on premium services.

By the way, I've been reading Fred Wilson's blog lately.  It's pretty good.  I'll post some responses to his posts in the next few days.
