Last summer I collaborated with Rob from Techvibes and Christine from Blue Lime Media to build the first version of Techcouver.com, a Vancouver transit map showing Web 2.0 companies.
Then Cameron from Reaction Lab got involved, and we had a much fancier, Flash-based version 2.0.
Techvibes has national ambitions, so with Christine’s help, they recently rolled out version 3.0. It’s based on Google Maps, is nation-wide and is no longer restricted to Web 2.0 companies. Check it out.

how can I add to it? I’m in Edmonton and it doesn’t come up with any listing. Bioware is the first that comes to mind but there’s a tonne of tech in Edmonton.
Wader: There’s a link in the top nav that says “Get on the Map”. Maybe they should change that to a more generic “Add to the Map”.
This is awesome! As a tech journalist, I am constantly under deadline to find a local company in a specific kind of field. This is going to help enormously!
