Opensim and realxtend projects have been a great source for me for a long time now (that's why I am crossposting). I started to publish my news blog http://cybertechnews.org about a year ago - happy birthday to the site! - and continued together with Ralf the shark and Simon Probert to create open source news site http://maxping.org and content site http://rexxed.com - the latest addition being the mobile twitter service http://TweetSo.me - which is not so much about virtual worlds, but still an interesting thing to do. We are going to see many improvements and exciting things during 2010 coming to virtual worlds, and especially to Opensim and realXtend.
I want to thank you all for contributing to open source virtual worlds and our publishing projects under Maxping umbrella and wish you very relaxing holidays!
