Thanks for the great topic Tim. I had wrote almost a year ago about wanting to start a STEEM style Air BNB. You can check it out here if you wish... https://steemit.com/travel/@intothewild/steemit-vacation-home-exchange
I would absolutely love to be the first person to do a STEEM air bnb, even if it is someone going to my place.

But I honestly think that is just the tip of the iceberg. I really love this meme showing how all these big companies got so big without actually owning anything that they were selling. Why not incorporate STEEM into all of these?

We are already (albeit small) on our way to being the next best SM site since FB. I think Air BNB would be the next easiest to tackle. Alibaba could be a STEEM style craigslist of sorts. And who wouldn't want to get picked up by a fellow Steemian than some random stranger?

Love the ideas here so far and the momentum STEEM has rolling already for 2018. I am not a developer by any means but I am more than happy to contribute to these ideas in any way I can if someone wants to run with them.
