What was your most successful site?

Megatuts.com. I used to own it and made tons of tutorials while submitting them to large tutorial submission engines like Good-tutorials, Pixel2life, etc... to recieve thousands of new visitors a day. Usually i'd get around 1000+ unique hits a day. Still now even though no new tutorials are added really, i see 500+ new visitors there everyday by looking at the stats. I do not own the site anymore (sold it). Now i own another new tutorial site not as good though .
