Screaming Penguin - Source Does Matter

So I have been wondering about this for a while. The "Social"aspect to every Google product, except YouTube, which was an acquisition, BLOWS. Google has Orkut, their internally developed Social Network site, but nobody seems to care about it. Meanwhile, Facebook seems to be running away with the whole SN thing. I am not saying Google needs to even bother with the SN market. However, there is a killer app waiting to happen:

contacts.google.com

Google has Parts 1 and 2 of the Exchange trifecta: mail and calendar. Now they need to get away from the shitty Gmail contacts and build a REAL contact management app. THEN they need to tie that into all the other Google products. Picassa, Reader Shared Feeds, Orkut, GTalk. They could all use a good contact management app. Moreover, as sites like Facebook start to offer Google contact import, make contacts.google.com give a FOAF export for other SN-style sites (Facebook, Last.fm, hell even Flickr) to use.

This has other benefits when viewed in the larger scope. *Shared* contact lists can become the basis for permission based Google Groups, or Exchange-like mailing lists in Gmail. Add in decent integration to docs.google.com and a little workflow and BAM, you have a SaleForce.com competitor.
