OpenStreetMap
Just started a Twitter account for Bristol OSMers. If London has its own, then surely Bristol deserves one too.
Tweet at @OSMBristol if you want something mentioned. If you sound trustworthy, you might even get the password!
On Friday 2011-04-15 did a walking survey up and down Stokes Croft. Entered into OSM on Saturday evening, along with Bing building outlines. Looks pretty good!
Walked Park Street and the Centre on October 19, noting all shops and other businesses. Added to OSM over the next couple of days.
Technique, as with Whiteladies Road, was to type stuff as I walk into the Notes app on iPhone. No GPS running; instead assumed roads are accurate and that I am filling in the gaps between side streets.

Spent yesterday gathering info for all shops in Clifton Village. Pretty complete now, including house numbers. Also land use in Clifton College. In the previous week I've been fixing up various Clifton things, and some in central Bristol.
