So I have a free WP blog at WP.com and I'm thinking about switching over and self-hosting the site I have up now instead of using the the WP hosted blog. I plan on still using the WP platform, but hosting the site myself. My question is, would I be impacted negatively in any way? Loss of PR? I'm very content with my sites' ranking, Does WP.com SEO the free blogs automatically? If so, I'm assuming i'd lose that? Should I wait until the site matures a little bit? Launched in June. Thanks in advance. Reps and Thanks given.
