I just 'quantified' my site with them a few weeks ago.
I guess the only two downsides to this could be that your traffic numbers will be available for all to see - if you come out ahead of your competitors that could be good. But if you are saying "we are #1" and then you find out you are not...then that could be a problem.
The script that you have to put on each page just adds to the page size although it is only 1,168 bytes - much better than Google Analytics at over 8K
In my case I only want to see how I compare to other sites like mine, but if they do not 'quantify' then the results really do not mean much.
If you sell advertising then you could PROVE numbers I guess.
I just wanted to try it and see what I could learn really
