If you own a wordpress blog and something happens and you start
getting a huge spike in traffic what is going to happen? You are going
to get a bunch of people looking at a blank page. with the stress of the
plugins in which you are running coupled by the traffic it will shut
you and your income down.

As autoblogers are main goal
is to protect our money site at all cost there is no better way to do
that then WP Super Cache. What this gem of a plugin does is cuts down on server load  by caching your pages as dynamic pages so when a user visits your blog they will see the dynamic page. Which will save on the database. That will drasticly reduce your server load time. You bring down the server load your chances of your money site going off line lessens. Protecting your investment for a little while longer.

So if you have a autoblog i definately recomend WP Super Cache . Besides that it is free. What better deal then that?
