Yes, I've found this business of blog items plunging off into Friendfeed very disconcerting, since I don't have an account. In a way though, it's no worse than plunging off onto an email list to which I'm not subscribed. The good thing in either case would be for someone to report (their view of) the conclusions of either discussion back to the place of origin, eg the blog. It seems a bit rude otherwise, if you'll pardon me: you tell some folks something interesting, then go off and discuss it privately with other folks, potentially coming to a different conclusion, but don't update the first lot. So we might say, CN thinks this, see his blog, when in fact he no longer does think this (I know, there's no promise that a blog post is a considered thought like an article, I'm just saying how it feels). I've tried this sort of summary of some discussions that have taken place on the DCC-Associates email list (which is not archived); unfortunately, the way I've tried to do it, using contributors' own words, it's a lot of work.
