Sorry I Missed Your Party
This blog trolls Flickr for photos tagged "party" and posts some of the more provocative ones. Occasionally there's video, but it's usually a Flickr photo - which often links to an entire set of party photos that probably shouldn't have been made public. I recommend checking this site daily, as it never disappoints.
There are a few sites like this out there, but this one posts the most frequently and, usually, has just the right balance of snarky and savvy. If this site proves anything, it's that having a copy of PhotoShop does not make you an art director, or even teach you anything about composition. You'll learn to spot the marks of an amateur yourself after just a few pages of this site.
The Fail Blog
Evidence of failure is what this blog is all about. The nature of the "fail" varies, and sometimes it's a little hit or miss. But, in the same spirit of Photoshop Disasters and Sorry I Missed Your Party, this blog rarely fails to entertain with frequent updates that help you laugh at others' misfortune (usually the result of their own ineptitude).
Considerably less hilarity than the previous links, but more about inspiring graphic design and photography which the sites' contributors find around the Internet (a lot from the Behance network, as it turns out). It's a bit like a visual tappas menu, with a slew of new tastes for your eyes to sample each day. Maybe that was a bad analogy, but take a gander anyway.
Of course, these and many others are always here for your perusal. Just check the link roll to the right for new additions each time you visit.
