What are the features of Ask Ubuntu??
There are a ton of features on Ask Ubuntu - However, the platform is designed to be "Documentation through Discovery". So you won't find a list of features - StackExchange keeps things "interesting" by always adding and changing features and letting the user discover how to use the site. If you're wondering "What things can I discover" you may wish to view your available privileges. This should give you an idea of what to look forward to and what you can do now.
I found askubuntu.com/review
This shows low rep new users, it's useful for guiding new users on how to use the site, etc. Low quality posts is pretty useful too -- though I suspect it's mostly useful for people who do a ton of editing and/or moderation than the average user.
More information on the parent meta.

I really like Ubuntu & the very helpful community. A website called 'Ask Ubuntu' will attract anyone with a query but unfortunately it's not at all clear how to navigate the site. It needs a Site Map and a simple Site Guide & a Users Guide. eg the Front Screen needs something like:
"Welcome to Ask Ubuntu.
1/ Pose your question in the box at the top left of the screen to see if it's been asked before.
2/ If not then Register yourself and
3/ ASK your question by typing it in the box at xxx.
4/ You'll find how to format your question by clicking on yyy which you will find at zzz"
Not only will this help anyone new to the site to use it: it might well increase the takeup of Ubuntu & other flavours generally.
I expect this has been explored before, but I can't find it [poor navigation skills? or sophisticated site design?!?]
