Whether you're a fan of logos or looking for inspiration here are three sites that are useful.
http://www.logopond.com This is a good site, where you can join and upload your photos as well. There are plenty of designers, you can talk on the forums, pick your favorites, maybe be a featured designer, and have your logo appear on the homepage. You'll see some heavyweight designers in the industry in the "Feature" section. It's worth checking out. Logopond has a sister site called Illypads for illustrators to showcase their work.
http://www.faveup.com This site showcases logos and unique business cards that were submitted and approved by the people at Faveup. This site is updated every couple of days, so it's usually current with new work. I like looking at the business cards a bit more when I'm on this site, because it's an element of the corporate identity package.
This site is similar to Fave Up and probably has some logos from there on here. This site wants to have only the best logos out there, so you can recommend a logo that you find inspirational or submit one of yours.
