I’ve mentioned I consider Twitter to now be infrastructure for short messages. Facebook is equally becoming infrastructure for recommendations.
Not that I’m impressed by e.g. Places. It’s yet quite feature-less and Facebook is not in any way exploiting its potential, and I wonder why Facebook doesn’t make applications like PalFinder, that I developed on a coffee break (admittedly a rather long one, with a cookie or two). Will Deals be as feature-less?
