I think it's a beautiful idea to make Steemit "physical" by sending each other things... and I believe it could easily become the prototype for an entire Steemit peer-to-peer marketplace... art, handicrafts, goods and services, all bypassing the whole "manufacturer-to-middleman-to-store" thing, and funded with Steem.
I had considered the idea of creating a "Postcard Exchange" on Steemit where members could send each other postcards from all corners of the world... the main issue is to have a safe-- but convenient and easy-- way to exchange addresses.
Lots of other things we could do, too.
Cool hat and shades, by the way!
Thanks for your great ideas. This has been a lot of fun and I sure hope that @papa-pepper gets the package that I sent him. We exchanged addresses in Steemit.chat and his is a p.o. Box so he's set up nicely.
