Thanks for the link, I always enjoy a good talk.
I use Pocket to save text to read later. Sadly, I don't know any similar program/service for video. I would love to have a service where I could send videos from youtube or a file or a torrent, and it would save the oldest one on my phone, so that I can watch it offline on my phone when going on the train.
If someone makes this, I'm def willing to pay you $5/month for it, and I'm sure many others are as well.
