Eh, a little bit, but I've gotten used to this new style, which I think is more professional than it was previously.
I remember the forum lag, though. You'd be cruising for one minute, and then all of a sudden, it lags, and sometimes you get logged out, or the site kicks you out until a certain time. Good ol' frustration. I also remember Serebii being more prone to Trojans/viruses than it does now. Which I think is a good thing it doesn't. My other computer had actually gotten infected from a Trojan here once. That was a pain to fix. Of course, Macs have a built in effective-immediately firewall, so now I don't have to worry about infections.
