The trend seems to be towards InternetTraffic but it's not easy to get in, I'm still waiting and it's been weeks (Frank Schilling's new venture, along with DomainNameSales.com, the aftermarket on the same site)
ParkingCrew and RookMedia are the new cool guys on the block, very similar comments I find for both. I have a bit of a problem w/RM since they capitalize the 1st letter and I won't go for that (Nameyourprice.com does not look good, neither does Ygh.com for an acronym, and there's no option to do all caps or all small letters, I also wish you could choose your template) ParkingCrew lets you choose up to 4 rotating landing pages and at least with them domain names appear as all lower case
RookMedia has some guys who were at Namedrive, Ed for example is at RM now and was the ND rep for DNF. Not sure about PC, they look European and I believe are based in Luxembourg. Voodoo is still mentioned as one of the new alternatives, and Donny uses the Google feed for this one, it's different from the old Parked.com which, as someone mentioned, merged with WhyPark and they're now called DomainApps, and still using Yahoo/Bing
I actually thought Donny owned both DomainApps and Voodoo until recently. The real bad news was that the old Parked.com technology/UI/API (no matter how your names performed there) was unparalleled, and still is, and DomainApps doesn't have it anymore, the new site looks exactly like the old WhyPark. I wish DomainApps were still using that technology, no one else even comes close and what you could do there you simply can't do anywhere else. I don't like the single template format DomainApps has though, which is unchanged from Parked.com (the double-click, rarely were you assigned the single-click), they have one single platform which is actually a single template where you can pick the pic and colors
I haven't tried Above.com but should. Apparently their system chooses which parking service is best for each domain, I had never seen a company do this
