Actually AROS is updated every day and is moving along nicely in recent times.
The website layout is a bit confusing though, the snapshots (which arent really updated anymore) are at the top of the downloads page, which at a glance makes it look like aros itself has stalled. If you scroll down beyond that you'll see the nightly builds. Additionally the main page status updates arent updated often.
...and, moreover, AROS nightly builds are DEFINITELY NOT what users want. They are good for developers and for anyone that want to customize everything from scratch. Anyone that wishes to install a usable system on their computer should look for a distribution instead.
