The closest thing to a meta-search site is Omgili
, but lacks all the other functions, and it's not well-known. In fact, if it wasn't for being included as an alias with FARR, I wouldn't be aware of its existence.
There's also Big Boards
, which compiles some statistics about forums, but it's a bit limited as many forums are not listed there (mostly because of the site focus). So I think it could be an interesting idea, not so sure as how to make it possible.
EDIT1: A search in Google for some information about an unrelated thing unearthed two search engines: WASAlive
, which appears to search in forums and blog comments to find out what's hot at the moment (Macbook Air, Tom Cruise and, Brad Renfro?), and BoardReader
, this one appears to be quite more interesting, with stats for the things you search, seems more advanced than the other
EDIT2: Rewrote a sentence in the first paragraph a bit, and removed a redundant phrase in EDIT1
