Bug-ridden and slow, but it has potential. I just wish they hadn't cut some basic features that now require several more clicks to access. No big deal; i've come to expect this sort of thing from the dA folk. A bit like most versions of Windows, they shoot for the moon with what sound like great new features, but there's always a fly in the ointment somewhere. Unprofessional.
I like it but I'm having trouble figuring out if someone sent a comment or made a picture as they both register. So I like it but I need to adjust a little.
And yeah, the whole message alert do-hicky bit is a tad annoying.
I HOPE they never get as bad as Facebook though, you're right about that!
