  • I have not received your daily or weekly e-mails in at least 2 months, is there a problem??

      @Lance Hall: It looks like you had been unsubscribed for some reason. This does happen automatically if you don’t open any of the emails over a certain stretch, I think like a month or something. We don’t want to be sending emails to people who seem to not want them. 🙂 I’ve re-subscribed you though, so you should get them now.

  • It would be great if you could setup the YouTube feed so it can be subscribed to using podcast apps. TED talks, for instance, have this feature.
