I’m a huge fan of well designed content sites. And by content sites I mean sites that rotate a lot of content (magazines, newspapers, etc.).
7x7sf is one of those sites, and I think they’ve done an excellent job with it. Nice big pictures (high quality) and lots of interesting things to look at. The site has a huge staff (a big media company), so it’s not like they didn’t have the resources to make this, but I just liked it.
