Honorable mentions for tackling part of the problem go to IPFS and Scuttlebutt.

There's a lot of people who understand the larger vision around the decentralization crowd if you can find them in the haystack of hypesters.

Say I'm very popular on twitter, and say I don't like somebody for whatever reason. If there's a reasonable expectation that this will result in them being mobbed by my less personable followers, does that count as incitement?

Or at what point does aggressive banter in good faith become an actual threat in [favorite multiplayer video game]?

If there's lots of low hanging fruit then a broad tax/subsidy makes sense, but if you need high levels of investment into specific things to make a difference, then use the tool for the job.

Which end of the spectrum incentivizing green behavior/tech mainly lies towards is left as an exercise for the reader.

For real-time subscriptions though, websockets (pardon my grammar) are wonderful. Hence why all the above will probably be ignored as they become a trend and people at large learn the sensible limits of what to use them for.

You've got some bugs to work out but this is a very fun and useful idea.

Had I known this sooner it would've sped me along considerably towards finding a lot of cool things that give me more motivation to program.

You might try setting up a simple blog and chatroom combo specifically for what you're learning and trying to get a few others to join in on some parts for the mutual support.

Worth mentioning is also the typical advice of teaching others being one of the most effective learning methods.
