I have no real opinion on intermittent fasting other than it seems to work well with ketosis. But I haven't quite intentionally experimented with IF aside from what I described in my video.
Sorry, I don't think I explained my idea well enough. Steem allows for subchains. Subchains are kind of branches off of the Steem blockchain that other applications can use. So if someone wanted to create an app that enabled people to trade their babysitting hours they could do so on a Steem subchain. Steemit Inc could facilitate the creation of such apps by creating a tool that automates that process. These subchains could use the identical Steem/SP/SBD monetary system OR it could use a monetary system custom built for its purpose. This is another service Steemit Inc could potentially provide; the expertise of how to build the right crypto for your application. This services a fundamentally different customer than Steemit Inc because anyone trying to build a specific community (whether it's a babysitting collective, home-schooling collective, book club, comic book trading club, etc.) is never, EVER going to look to Steemit to serve that function. Steemit is only a social network. Mind you I am not saying that work should stop or even slow on Steemit.
As far as licensing or anything like that, this would be an open source project, Steemit Inc would provide the tool for free because that would maximize adoption which would maximize the demand generated for Steem (subchains still use Steem).
