to or not to specify font sizes

Now this is really serious. There are some who say that a font size of 10 to 12 points would be good, some others who say that font sizes should be specified in percentage of 80 to 90% and some others who are against specifying font sizes. I wonder which one would be correct on the web usability point of view. Any help?
 
Definitely stay away from absolute font sizes for usability - sure, 12 point may be a 'normal' font size for you, but for some people 12 point may as well be 1 point.

I'd suggest using relative font sizes - whether percent, or -1/+2. That way, you can say, this is a bit bigger than the person's usual font size, that's a bit smaller, and you keep the relative emphasis with font size, without messing with one person's need for at least 16 point fonts, or another person's objection to anything bigger than 10 point...
 
While you are at it stay away from fixed page (table) widths as much as possible... for similar let-the-user-decide reasons.
