Do your stored up revisions affect your page load speed?
If you have lots of revisions of your posts in Wordpress stored up, could that slow things down? And if so, is there a way to delete all but the current one?
Also, I read that you should keep your plugins to no more than 6, for the sake of load speed of your pages. I find I really need all of the plugins I have, but I'm at more like 9.
