I felt old a few years ago when the eye doctor first explained progressive lenses to me. I remember saying "so...they're trifocals," to which he responded..."yes, they've been rebranded."

Well, he made me feel old again at today's visit, although this time without the humor. He explained the concept of "office glasses" to me. Essentially, office glasses have lenses with a larger zone for intermediate distances, and smaller zones for far and near distances (progressive lenses typically have a relatively large area for far distances, a smaller area for intermediate distances, and an even smaller area for near distances). You use your office glasses during the workday while most things you're focusing on fall in the intermediate distance category. This reduces the time and strain involved in moving your head around to land things in the relatively small intermediate zone of "regular" trifocals (sorry, "progressives"). You leave your office glasses, well, at the office and switch to your regulars, and their larger zone for far away distances, for the drive home.

I hate that this makes perfect sense to me.

I'm glad to see Dave Winer post about the reliability of good 'ole fashioned feeds for working together and the wrongness of adding new hurdles to interop. I've built RSS into Daystream from the beginning, and continue looking for ways to use it.
