I set up this map
some time ago for the Hyperlocal Allinace group on Linkedin, and have now started adding events to it. I'm realising it's a bit tricky to add everyone by geographic area, so if you want to add yourself or anything else to the map, please feel free :)
If text is easier for you, there is also a text version available by using the RSS link, this doesn't work in all browsers but Firefox seems OK.
Here's a shortcut link to the map as well, as Google maps links are a bit unwieldy: http://icanhaz.com/uklocal
