> The law is pretty clear about this--facts can't be copyrighted.

While it is true that "facts can't be copyrighted", it's unclear that Craigslist listings qualify as facts in the relevant sense. (The singles listings, for example, surely don't.)

> Someone writes down the information and has their own meetup for people who couldn't make it to the free, public CL meetup. Whats the difference between that and what padmapper is doing, except that padmapper is getting the information second hand?

Getting the information second-hand seems fairly significant.

Don't get me wrong - I think that craigslist should be disrupted, but I don't think that you should just do the easy parts.

Note that the NYT has a dog in this fight - Craigslist has "disrupted" the newspaper biz.
