I wasn't sure where else I should ask this question, but I was hoping that some of you cold recommend some of the most active, most useful and most informative websites out there that discuss the following subjects:

TV Shows:
  • Shows, content, lineups, quality, providers, etc...
  • In particular, I would love to find a website that was entirely focused on TV commercials and hard-to-find video shorts of the kind
Websites:
  • Forums that not only discuss sites from a variety of topics, but ones that help users discover these websites...
  • Basically a place to chat about what's the best online backup site, or which site gives the most unbiased reviews, or what political sites reveal the best dirt, etc...
Searching the Internet:
  • I don't supposed anyone knows of a good forum where tips and techniques for searching then net are discussed and exchanged...
  • Better yet, anyone know of a forum in which people can post a really difficult topic that they're searching for information about on the net, which then becomes the active challenge of others who are viewing the forum to see if their search skills are good enough to find it? (there are a couple of things I am trying to find out there which has eluded my intermediate search skills using Google and other search engines)
Any suggestions would be greatly appreciated...Thanks!
