It is for these reasons that we’ve started ExtraBITS, in which TidBITS editors will wax blogosophic about the kinds of subjects you enjoy reading in TidBITS. The pieces will be shorter, breezier, and yes, less complete and exhaustively researched. They should be, in their own size and context, no less useful or enjoyable than our regular weekly content, just different.
And yes, it has an RSS Feed as well.
