Slightly unrelated, you IMHO should always use a solution where you can use your own domain name, so you can rescue your content to your own server or another provider and keep your links alive (in case a service is shutting down, your preferences change, ...)

I personally run a DIY-thing, but that's not because I necessarily think that is a good idea ;) If I weren't using that I'd either use a static site generator of some kind or pay for Wordpress.com.
