I have used BlueLight, Netzero, and AltaVista FreeAccess. They're really slow and there's a lot of disconnects and slow connections. But, AltaVista FreeAcess seems to be the best. I think NetZero seems to be the worst free one I've tried. The ad box is huge and If you move it around because its in your way, sometimes It will disconnect you for trying to avoid seeing the ads
. Also, there is the "NZTV" thing that shows a TV-style ad when you connect. Bluelight is so-so, but it gets irritating with nothing but K-Mart ads all over the place while surfing.(You start off in a K-Mart My Yahoo! page with K-Mart "special offers" on it, when you connect, It shows a 1-2 minute K-Mart tv ad, and the ad box always has K-Mart all over it) It's just really annoying.
