Web 2.0 activity in Portland is still a big interest area for me and a number of Portland sites popped up this week. Seems things are really getting going around here.

TwitterWhere

TwitterWhere is a cool new project from local Portland developer Matt King. Similar to how Local Signal tracks an assortment of feeds for a specific city to filter and discover news, events, and people, TwitterWhere tracks Twitter activity for a given location, making it easy find local breaking news and other Tweeters. (Silicon Florist and Read/Write Web coverage)

ChoiceA

ChoiceA is a new national real estate FSBO site (Silicon Florist and Read/Write Web have more).

Platial

Platial made a pretty bold move it seems in acquiring one of their direct competitors in the social mapping space who had been doing better, traffic ranking wise. Should be interesting to see what happens with the combined companies.
