Mashable is a good source of leads – on a bunch of topics related to online activity. Today they’ve put up a post that lists more than 40 “free blog hosting” sites.
I use WordPress and I run it on my own servers, as well as running it for a dozen or so clients. Gives me a lot of control, and more features than I would have if I used wordpress.com as a host.
But I get asked all of the time where one can find a good (and free) blog-hosting site.
So, Mashable has their 40+ answers to the question.
