A few people have been asking when Awasu will support Atom. Well, it's coming soon (as soon as I drag my battered body from beneath the weight of all the other features I'm working on right now :roll:) but in the meantime, you can still subscribe to Atom feeds right now, using XSLT.
BTW, the next beta is in the final throes of testing and should be out in a week or two. It's looking way excellent - woo hoo! 😀
