Easy and stable
Very good wiki image. One-click to install, easy to setup, easy to use. Quite stable -- I've used for 4 months, without major problems.
Hope it can upgrade more fast following the Tiki Wiki software itselfing.
Great software and nice and easy image to deploy from. Within a couple of hours of the EC2 being created, I was able to set an internal intranet system up and running.
