I run <a href="http://breakingbits.net" rel="nofollow">http://breakingbits.net</a>, my security consulting blog, on WPEngine.<p>I highly recommend it. Wordpress gets a very bad rap with security but as long as you generally disable comments, are paranoid about plugins and themes, and update as soon as possible, you're about as safe as any other platform.<p>It also gives a very nice platform for customization and development, which unfortunately a lot of blogging platforms don't support. I can quickly sftp or ssh for whatever I need, and setting up Bigfoot.js footnotes was a breeze (among other code snippets).<p>I recommend WPEngine because, while they are a bit pricey, they have generally excellent customer support and take away a lot of the mental overhead of running Wordpress. I first started using them after a glowing recommendation from Patrick McKenzie (patio11). They're also great for managing backups, security updates and plugin safety. The only caveat I can name is that if you want SSL for your blog, you'll need to jump to their second plan or higher.<p>A bit off-topic, but good advice for this is to just generally not stress about it too much. You're not shipping blog posts, and while you'll get consulting leads or job offers from it, it's secondary to your main work. Maximize on content delivery.<p>Find something you're comfortable with and stick with it.
