That is the best feature of Maxthon. Whenever I use FF or Konqueror, I
constantly catch myself trying to drag links to open it. Since I do a lot of
state and federal government work, I stick with IE, as they have policies
against other browsers.

I am on shared hosting, so I don't have access to top or any other real
stats, but it does appear that the actual server load has decreased some.
Before I installed BB2, there were times it would take 10-15 seconds to load
the site. Now it might get to 5 seconds if I am getting hammered. I haven't
really torn into BB2 to see the inner workings and figure out if it helps
with actual load. It certainly did reduce the number of spam comments
appearing in Akismet.

I believe where BB2 comes into play more is it prevents these spam programs
from crawling the actual site and finding whatever links they can.

I have been playing with a similar idea in my head. Since these spam bot
programs don't generally execute Javascript, I was thinking of coming up
with a way using a combination of a hashed time key and dynamically
inserting the form action. This would of course limit people commenting to
being only Javascript users, but that is the price to pay. 

To further reduce actual server load, it would be wise to create a dummy
wp-comments-post.php file that is blank. That way the rewrite rules would
bypass firing up the Wordpress core and in turn keep processing cycles down,
by not generating the WP 404 page.
