How do I remember all my usernames & passwords?

I've recently turned to a password manager site. I know that won't work for common users, as the thought of signing into a second site takes waaay too long... But is there any reason a more tech savvy person wouldn't?

For passwords Nate suggests combining values from the name of the site with memorized values. Any security experts know if this will result in a reliable level of security?

this isn't bullet proof .. but will counter lots of automated attacks ... plus you would have to know the credentials for at least to sites and then try two figure out the algorithm
