If you want to establish authorship (have your photo and a link to your Google+ profile appear next to content you’ve created, in Google search results), I’d recommend adding Google Authorship markup to your site. See more details here. WordPress Bloggers, check out this plugin. If you have Genesis Framework, even better! StudioPress makes it easier.
I’m on Google+. Mostly for professional/networking/tooting MM/business purposes.
Add me to your circles!
