I just noticed through the hosting usage statistics that we have now crossed the symbolic count of 100 installs of the hosting module (which is the frontend of Aegir). It seems that our presence at Drupalcon had a great impact, as we had only 64 installs before the conference.
81 of those installs are running the latest 0.3 release, which still seems to be our best release to date. There are only 4 installs of the 5.x series, which is a good thing, considering it's at end of life (even though Aegir can of course still install Drupal 5, the frontend is now fully running in Drupal 6).
This also mean that there are still 20 people not running the latest versions. We'd like to hear from you people. What is keeping you in the dark? Having trouble upgrading? Not sure where to start?
To all those new users we have: welcome to Aegir! We're happy to count you on board and hope the project will answer your needs. If it doesn't, please let us know so we can improve it. If you find bugs or issues, don't hesitate to share it with the community (see the bug submission guidelines for more information).
Otherwise, I wish to thank everyone to their support. It's encouraging to see the project go forward with such energy.

D5 stats inaccurate
I'm sure the D5 stats are inaccurate. It's probably less common for people to download the update_status module for D5. I for one am still on D5, and don't have update_status on my aegir site.
Congrats nonetheless!
Too busy!
I've gotten .3 to work, and am very excited by the possibilities... but everything else at my job has kept me from getting back to it.
glad to be one of the 100, glad to do my part to help it grow.
