I would say blogger too. Another one you may want to look into is Tumblr.
I tried a few others, like Jimdo and Ucoz, but they such if you want to use them without upgrading/paying. I mean, you can make your blog and everything, but ucoz will keep deactivating your site all the time, and jimdo is also shit for some reason, can't remember exactly why as I haven't visited that site in a while.
Use Blogger, check out Tumblr.
