Of course it eliminated my problem - hence it fixed it. This slow execution error didn't appear in most of my posts - only in those which had revisions. I probably have a slow host, but it should be expected that WordPress handles it correctly with little to no problem. I believe the slow execution error is a big problem as I was unable to edit my post.
Better yet, Otto, is if the user didn't have to add a line into your wp-conf. Maybe I haven't been in WordPress' community for a long time, but I'm sure a simple <url to disabling x option> is much faster than needing to download your wp-conf, edit it, and re-upload it.
And as said, theres no such thing as perfect software. One person can say one thing, another the opposite. Options are blatantly options - to toggle something you don't want on or off. Of course, some people might like things with less options. What does that do? Limit the user capabilities. Heck, when I see "Writing" in the Settings page, I immediately believe that there should be something to toggle Post Revisions.
Now here's my new idea in case you missed it:
Add a link into Post Revision page on the how-to disable post revisions. That would've also helped muched.
Why wasn't a 'hand written' plugin for disabling it made with the package then? That would have greatly helped as well.
I'm not entirely sure what host you use for WordPress.com, but wow. And it's alright; I have knowledge of TortoiseSVN and such to not screw things up.
I know that your plugin can disable it, but I more or less know how to code PHP. All I'm saying is that I want things to be simplified. I don't wanna go around the net or WordPress.org to disable something compared to looking around and carefully reading the settings. It takes too much time for me.
Now to be blatant, here is what I request, in case you're too lazy to read:
A. Add a link on the how-to-disable-revisions in Post Revisions page.
B. Do not compare two post data when editing a post. Do it only when you click a post revision.
