Geek to Live: Flickr Advanced User Guide - Lifehacker:

Lifehacker presents a Flickr advanced user guide - some nice stuff in there that you might not have stumbled across before now.

Also:

The Top Cameras is a list of the cameras most often used to take photos that are uploaded to flickr (as indicated in the photo's exif data). Nice to see that the Nikon D70 is so widely used - makes me feel part of the 'In Crowd'.

Also from Lifehacker there's the Right-click send to Flickr OS X Automator action - what it does should be fairly self explanatory.

While not on Lifehacker (but I found it via there) is 10 Flickr Hacks.

DLSRBlog is running a Picture a Day Challenge (with a second post that has an update).

Via digg is the Windows Flickr Background Switcher.

I've mentioned this one before, but I think it's well worth a second link: Are You A Pro? There's some great images coming up on this site, like the one above.
