I used WordPress since 2009 when I just stumbled across it. Now I've stumbled across many companies (Wordpress.org) that use it as their blogging CMS of choice, so I just stick with it.
If you want to post stuff that is more likely to get random traffic, I'd wager tumblr is your best bet with all those whatshouldwecallme and whatever nonsense. They're funny now and again, but not the blogging style I'm into personally or professionally.
