Hi Andrea, nice WP blog. I'm also a WP user, and I'm very happy with using it. I really liked your theme so I had to go and look for myself where you got it from.
I've sometimes thought about getting a premium theme but have stuck with the free ones and customized what I could. It mets my needs for now. I like the clean open spaces, the uncluttered layout and the soft colours on your blog. The fonts are very nice too. It's a very readable blog.
Good luck with your readership!
