If you are saying what is the next generation (i.e. Web 3.0) search engines I think none of these are. These are all just better version of 1.0 or basic 2.0 engines. Searchme.com and RedZee.com and Ask.com are all closer to 3.0 search engines (but even that is pushing it a bit).
Looks pretty cool actually. Although Ms. Dewey gets irritating after the first minute or so. Okay, so firstly: My site, the one with approx 9000 backlinks, PR4, sitelinks in Google...gets overcasted by our .com version, which has about 10 pages of utter crap. Nice Links open in a new window...very irritating for a searcher, especially with Ms Dewey rambling on in the background. It's slow. Dewey's screen on her phone doesn't light up when she dials - obviously switched off! Still, I have another fault to pick: © 2007 Microsoft Corp. When will all these corporations update their copyright notices?! Ah, I love the finer details Although, back on track - it's just a standard search engine which produces more than odd results!
