Second, he's relaunched A Slab of Glass. This was a great podcast he did with Chris Lawley, but now it's been relaunched as an interview show. I was lucky enough to be invited on as a guest so that episode will be coming out over the next few weeks.
I've always enjoyed Jeff's insights, but he's jumped platforms and focuses a lot. At one point I had 3 differenent RSS feeds in Unread that were all delivering the same content. If you listen to my podcast episode you'll hear that we talk about this and I challenge him on what he'll stick with.
Like I said, I'm subscribing to his newsletter after the track record of months of sticking with it.
