The pixel count is important, especially if you plan to print any pictures. However, if your main use is to post pictures on the Internet , then it is not so critical becasue your monitor etc. has limits. You can get good Internet pics from a 1.3 or 2 pixel camera.

At least that's the way I understand it. Correct me if I am wrong!

One word of warning - you may get the dreaded "new gear jinx" after your camera purchase. I just bought one myself, and have not caught a fish since!
