I'm using tumblr and find it's very easy to handle plus they have a lot of templates you can use and adjust to your needs. For the comment function you have to requister at disqus though, but that takes only about 2 mins.
I have been using Google's blogger in the past and it was also not bad though I find tumblr more user friendly, especially if you want to blog a lot of pictures and/or videos.
