Well, not really a list yet, but here's one thing I'd like to see:

I recently resumed a childhood hobby when my wife gave me a Digital SLR camera as a gift. I haven't done photography except for the typical party and tourist shots since I was a child. 

There's quite a lot to learn.  Now, when you take a picture, your exposure, aperture, focal length, ISO speed, and a ton of other information is saved with the metadata of the file. I've been reading some books on photography techniques, but learning by doing seems to make it more fun. 

Flickr extends the pleasure of the hobby by allowing you to build friendships and have others express their opinions about your pictures.  I'd love to have a page on Flickr that shows me a view of my picture thumbnails, with the following information below the thumbnail in concise form:

• View count
• Favorite count
• Comment count 
• Exposure
• Aperture
• Focal length
• ISO Speed

I'd use this to view my sets much like a "study", so I can see how different settings affect the picture.
