1 year, 2 months ago: @jasonwiser I’ve seen a few people (most notably Chris Brogan) move from Facebook to Google+. And I know that some photographers have seen better response from Google+ than their blog. But overall, you should keep all of your platforms and use Google+ in addition, not as a replacement.
To echo others, your self-hosted blog is yours. You don’t have to worry about the design changing without your go ahead (like Facebook losing default tabs in the new Timeline profile) or violating terms of service (except that of your hosting company which is usually pretty lenient compared to social networks). Plus, there’s customization that you can have on your own site that you’ll never get with a social network.
