Very good news for all directory owners and best of luck to Matt. I really really wish I had the money to buy it myself
FWIW, I just saw another directory on Sitepoint bought by Web Pro News. As well, at least 2 of the directories mentioned by CReed were just recently bought by Web Pro News. I find it really interesting that a large company suddenly is purchasing lots of directories... Also, I believe that they "monetize" their directories (at least at this point) primarily through a newsletter rather than submission fees.
Anyone else starting to receive unsolicited newletters? Check out the option at the bottom - by opting out of the newsletter, you're also removing yourself from the directory.
