A few of us Platial folks will be hanging out with many other geohacker/geowanker types this weekend at WhereCampSF down in Sunnyvale, CA.
Yahoo is graciously hosting this unconference, so if you are in the hood, come swing by, see what's happening, sit in on a session, or lead one yourself!
Oh, and Platial is also a Proud Sponsor of the event.
I'm also putting together a map of transportation and related stuff around the area.
If it's useful there is also a mobile version of this map here
