WikiPedia View Page History Tools & SEO Tool Creation Contest

I have not tried them out yet, but Andy Baio had a contest for people to animate the history of WikiPedia pages.

the results are here:

• http://phiffer.org/projects/wikipedia-animate/

• http://gleepglop.com/journal/articles/2005/06/16/wikidiff
• http://ejohn.org/projects/aniwiki/
• http://en.wikipedia.org/wiki/User:Colin_Hill/BetterHistory

I chipped in on that contest, and like the idea enough that I think we should have something like that for search and SEO, where people request open source tools be made, and we have competitions to see who can make the best ones and then pay them for it. Thoughts on that idea?

What search or SEO tools would you like to see be made?

I might start a weekly or monthly create a free tool thing next week. It could probably be a fun and useful project.
