About the Utility
Back in May of 2009, after using Twitter actively for around a year, I had an inkling that a disproportionate percentage of my friends were from the UK. I cannot say exactly why I thought this, but I wanted to find out if it was true, so I did some Googling to see if there were any sites that would map your friends for you. I didn't come up with anything, so I decided to build something myself.
Thanks to the availability of APIs for Twitter and Google Geocode and Maps, and open source projects like Pedro Claudio's ColdFusion Twitter Lib and Ray Camden's Google Geocode, as well as the Google Maps API Utility Library, I was able to bash something together in no time at all.
There is an issue with asking Google for location information via the Geocode API so I had to intentionally slow down the messages that were being sent to it. That's why the process takes so dang long. There is a pretty status bar, done using the jQuery UI project's Progressbar widget. At the end of the lengthy process you'll see a map, as well as an ugly report showing exactly what happened when Google was asked for your friends' addresses.
This whole thing was written nearly a year ago, and I'm just now skinning it to fit in with my blog. It's certainly not perfect, bit it's still pretty cool.
