Just for the heck of it, I wandered over to the Alphaville Herald only to discover that the latest post there is sneaking up on a month and a half old.
The buzzword is "blog fade". Burnout, finding another more appealing activity, having to give precedence to something else... for whatever reason, the articles slow and then stop. It happened to me with Pectoral Virtual Fashion; Maggie Bluxome did, and still does, far more than I was doing and did it far better, so why continue? I don't know whether that applies here. To know I'd have to know what the heck the Herald's purpose is, or was.
That said, though, it is a shame, unlike What the Fug. There for a while, the Herald had taken to writing interesting and worthwhile articles, a kind of last hurrah.
