yes but can you use your own domain name
This is the best way to run a blog - on your own domain and hosting.
For example go to the likes of blacknight hosting - buy your domain and buy your hosting - together for less than €100, check their site for prices.
They a one click install - really more like three clicks - dead simple. This will install your WP blog. Then you need ftp access, set that up, download from wordpress.org or where-ever your preferred theme, then download some plugin like seo for WP, they are many, but this is the most important one.
Up load both of these to your site with ftp and your in business. Setting up a blog is the easy part - the hard part is continually having something to write about, and writing when you can't be bothered.
here is an example of a small (unfinished) site using WP and pages.

Best of luck.
