Sorry if this has been discussed here before already. I tried to search for it, but couldn't find it.

In Matt's blog here http://blog.mattmecham.com/archives/2006/0..._22_update.html

it says

there's a fairly sizeable new feature that we're really pleased with. I'm not going to say what it is or post cool screen-shots because we want to keep this underwraps until we're ready for the first public beta. We don't mind sharing our forthcoming features but we don't want to see this one appearing anywhere else first as I'm fairly confident that our competition will adopt this new feature for their own products.

is the profile/buddy system thing this fair sizable new feature?
or is there something else that I haven't noticed yet?

the new profile and friends system is the new feature Matt is talking about
