Site called "Tech Support Alert" publishes excellent list of "46 Best-ever Freeware Utilities".
If you are at least modest tool freak you probably know and use most of them, but it's allways nice to have a list handy to find champions in the fields you are not an expert in (like "Best Free Anonymous Surfing Service"), or to find who is #2 if you get in trouble with current tool.
Best way to stay in touch is to feed, but you can also subscribe to mailing list.
