The change should have been completely transparent and invisible to you, so here’s the info: I’m running Wordpress now.
So that’s the fourth time I’ve switched blog CMS this year. Movable Type → Wordpress → Textpattern → MT again → Wordpress.
The main reason for switching is that the comment spam problem for Movable Type has become completely unbearable. It can quite literally kill a server. MT-Blacklist helps, but has a flaw that allows some comment spam to pass right through it.
And then there’s the whole “rebuild on every comment” aspect. If MT gets hit with 50 spams in 10 seconds, that’s 50 mt-comments.cgi processes that are all rebuilding a page. Sometimes the same page.
The TextDrive servers can easily push 20,000,000 hits per day. Yet mt-comments.cgi can effectively push the server load up into the 300s. This data speaks for itself — 94% of the hits are to mt-comments.cgi. 3-400 of them are proper comments, the rest is spam.
Wordpress and Textdrive are dynamic. There’s no page to generate every time a comment hits.
I still get spam, though. Spammers monitor web services like Weblogs.com and go spam them as soon as they see an updated blog there. I get some spam every time I write a new entry.
Enter Spam Karma. So far it’s stopped spam dead in its tracks, and this far more CPU efficient than MT-Blacklist. It works great, and the focus is to require as little interaction as possible from the blog owner.
In closing, Wordpress has matured immensely since I last tried it. This will be my weapon of choice for quite some time now.
