I have started using Flickr in the past year, it can be a lot of work adding tags to thousands of photos, but it is great for searching them later. I've also begun adding "Special tags" to some of my photos, those photos I have of WDW trash cans I've added the simple tag of wdwtrash (with no spaces), for bathroom photos. I'm adding TOTVKOTW which is a very long acronym forThrones Of The Vacation Kingdom Of The World, I've still got a lot of photos to label but I just though I'd share this for those of you who might also be interested in unusuall WDW subjects. I'll have to look for groups dedicated to these subjects on Flickr or start my own perhaps (also ones on the ships of WDW another favorite of mine) but for now I have plenty to keep my hands full. While I'm at it here's the link to the site of a guy who has a page on WDW trash cans: trash cans of WDW http://joel.at.wdw.online.fr/Bonus/Trashcans/
Brian, I am also a person who feels he gets his money's worth out of flickr by dumping thousands of pictures up there (pretty much all of disney). I am now more diligent about tagging, but wasn't when I first started. I don't think I put any creative tags, such as yours, on my unusual subjects. I like trash cans as well, bathroom signs and signs in general
