For me personally, it's easier to create a layout on Zoints than MySpace. The site doesn't seem to get bogged down like MySpace or even Windows Live Spaces does. The only thing is I haven't seen a lot of traffic on my page yet...it's only been a month though. I like the community feeling and David (who's also a member here) seems very personable and helpful.
Has it helped the stations? I don't know really. I'm guessing it hasn't hurt. I've seen numbers for Renegade Retro higher than months past as of late.
