I just noticed that Seattle’s Robot Co-op, makers of the very-cool personal-public to-do list 43 Things, released a spin-off of sorts called 43 Places into the world this summer. Where 43 Things helps users to plan what they want to accomplish, 43 Places asks them where they want to go.

While the site has only been public for a little over a month, it is already developing into a really neat resource. In addition to letting people keep track of their travel aspirations and achievements, it is a user-powered city guide and source for soliciting local advice. For instance, check out Seattle’s “wanderlust” page [43p] — it’s a directory of the people who live here, the places they love, and their reviews of local attractions. There’s also a page for people (currently 301) who want to visit Seattle [43p] that includes advice from recent visitors and questions for locals.

If this description has failed to intrigue you, please just point your browser over to the site and start clicking on links. This sort of user-powered collaborative knowledge type thing is one of the more thrilling uses of the web. The only problem is that the fun of contributing might get in the way of ever finishing your 43 things.
