I’ve added a lot to the statistics side of TweetDonate. All clicks on links are now being geocoded (courtesy of http://geoip.pidgets.com/ and http://www.maxmind.com).
An interesting discovery of improved stats tracking is that I’ve discovered that there are many bots operating on the Twitter stream. Every link that is posted causes about eight or nine bots to visit the link within a minute or so.
User agent, host name, referrer, twitter followers and more will soon be available.
