re: "what does "stepped in" mean? Generally, it's difficult to convert the assets of a nonprofit to those of a for-profit."
it seems to me that the real asset was not monetary (not at the point of transfer); what he really transfered between the companies, from the non-profit to the for profit was *traffic*! -- traffic that the *for profit* craigslist was able to monetize.
here are some things that craigslist did NOT deny: (page 2nd,point 7 of craigslist's response to ebay's complaint) "it is admitted that Mr. Newmark formed 1010 Cole Street inc. ("1010"), which is a predecessor of craigslist, that Mr. Buckmaster was hired and received shares in 1010 and later craigslist"
