Cool emerging web technologies

I saw this on Eileens blog a week or so back and thought it was a pretty cool idea. Obviously I have no affiliation with ClustrMaps but thought it was a great way of visualising who in the world is reading my blog and example of (IMHO) what could be considered a "Web 2.0" application. Now that I've had the tags on my blog for just over a week, the map is starting to take shape - this mornings view is below and you can see the latest here. It'll be interesting to watch it grow over the next few weeks, particularly to see if any polar bears are tuning in :)
