I am intrigued that so many of the high-profile geekocracy (who ought to know better but are apparently dim-brained slaves to digital fashion) seem now to be using Google+ as their preferred blogging platform. Why would anyone do that? Apart from the antiseptic anti-design imposed on everyone, there is no guarantee that Google+ will be any longer-lived than Buzz or Wave, or that it won’t suffer outages or catastrophic data wipes. I prefer to publish under my own domain names, with software I manage and control: I own the database (and local backups of it). I rent the infrastructure and can move my data wherever I like in 24 hours or so.
Of course, my way costs some money (but not much), and some technical know-how (rapidly acquired), while Google+ is “free” and easy. It depends on how much you value your own data. Is it less valuable to you than $10 or $20 a month and a few hours learning ftp chops? Okay then, carry on as you were! Me, I also happen to be a paying user of Gmail (through Google Apps), because that gives me more storage and a service-level agreement. (Because I’m an “enterprise” customer, I can complain when things go wrong.) Even then, I do as I would do if I were using the free version of Gmail: I back it up to local storage (over IMAP).
