Any reason why you couldn't set up some guest editors and contributors with requisite privileges?

Oh, it's technically do-able, sure (Wordpress makes that sort of thing quite easy; even LJ can probably do it with communities) -- maybe I just haven't found a blog that works like that & has the good content, yet.

I suppose the other point is that individuals make their own 'magazines' like this by subscribing to the blogs they want (and there are even services which let you select a load of articles & shove them into a PDF so you can make a 'news-sheet' of your own to read on the tube etc), but to me that feels too singular -- there's something slightly more joined-up about a group of individuals writing for the same magazine (and something slightly more community-ish about reading the same magazine as other people).

I think the concept I'm groping for here is the idea of editorial oversight, which is something that the internet publishing revolution seems to have devalued (indeed, the idea that people might even self-edit a little bit seems to be losing traction).

I continue to be surprised but delighted that you enjoy what I write!
