Matthew has a blog and he's planning to switch his webhost from blog.com. The servers are down at blog.com sometimes and he wants a reliable host.
Leo says that Tumblr is a good, free choice with a lot of templates. Good for a free blogger. Google has Blogger. There's also WordPress.com. All are free options, but he's limited to the templates they offer.
If he's willing to pay, then there's a good option with SquareSpace.
