Much better than their Flash interface. But completely broken in Firefox 3.0.x (under Red Hat; can't advance past the first page and there are no pictures) and the fonts are too big under Iceweasel 3.5.9 (under Debian). Until they stop requiring a log-in to download the original PDF so I can view the content in a decent viewer, I'm going to continue cursing every time I accidentally follow a link to scribd.
