Stop me if you've heard this one before

Hey!  Ever heard of an awesome website for selling or buying stuff that has the following features:

1. Is free
2. Is easy (no logins required... just a valid email address)
3. Is local, so you don't need to deal with shipping
4. Lets you edit and revise your ad at any time
5. Protects your email address from spam by using a privatized contact form?

Why yes, I have!  Obviously the wildly successful Craigsl-- oh wait, we're talking about these jackasses, who plastered their signs all over Capitol Hill on Saturday? (this one at the northeast corner of E John St and Broadway):
Congratulations UsedSeattle, you've just taken a wildly successful business model and done a much worse job of presenting it, with neither the critical mass nor the site layout that makes Craigslist so popular... and to top it off you managed to advertise in the most assholeish way possible, by plastering big coroplast signs on every signpost and tree in the entire neighborhood.

On the bright side, people in the neighborhood ripped down nearly all of the signs within 24 hours, so maybe all hope is not lost.  One can only hope they're now being offered in the 'free' category on Craigslist.
