Allen Morgan, meet your perfect idea-recycling resource. Business 2.0's Om Malik points out a useful list of dot-com ideas — all of which are now ghost sites, enshrined in the Museum of E-Failure. Check out Adcritic.com, which feels (but doesn't look, thankfully) like today's Adrants or AdLand. Or boo.com, which — wait — no, that one's coming back from the dead. Incidentally, is that girl on Boo.com supposed to look like an extra from Buffy the Vampire Slayer?
