I've been having a long conversation with Magic Speller about the pros and cons of Awasu compared to some of the other popular aggregators available out there. I won't quote any of it here but it's worth a look if you're interested in some of our future plans for Awasu and philosophy behind the current design and feature set.
And don't forget that each of our forums have RSS feeds so you can subscribe to them in Awasu and be notified when somebody posts something. Just look for the big orange XML button at the top of each forum's front page. And if you register (it's free), you will also get email notifications when somebody replies to one of your posts.
