axel, thanks for this - really good points, and all of this has occurred to me too.

Couple of things: Facebook is populated by a wide range of people in my pre-existing social networks who are not what I would think of as 'internet' people. They wouldn't have blogs, ever, or update wikipedia, or have flickr accounts, or whatever - they're on facebook because of the way that 'social network markets' work, if you'll forgive me. I have similar concerns about the 'lockdown' that is associated with a monolithic proprietary platform, though.

To take up your other hint, I'm not sure why I'm not blogging much right now, other than feeling that every sensible word I write should be in an RQF-able 'output' somewhere, and feeling under so much pressure work-wise that long-form prose seems like an enormous effort, and also the fact that my blog was a fieldwork diary for my PhD most of the time, and now that's over. And perhaps, to be honest, my imagined audience for the blog is not so different from my facebook or twitter network - so that a lot of what I used to blog about: personal, everyday stuff intermingled with a few research ideas - happens in a more piecemeal and distributed fashion across a variety of internet media now. So that I'm personally re-evaluating the purpose of 'scholarly' blogging - it's a reflective hiatus more than a stoppage, though. I think. Anyway, thanks for posting this, so I don't have to!
