First of all, this was an excellent and useful read as a newbie to cryptocurrency in general, much less Steem. I'm still a little unsure what the relationship between Steem Power and bandwidth is. I do understand as a general rule why more bandwidth is needed as communities grow larger, but why does that necessitate buying more Steem Power? I guess my next question there is, buying it from whom? Forgive me if this is a silly question; my knowledge of both cryptocurrency and general economics is pretty shaky.

Also, while I understand the value of Steem Power transferring to newer communities to help them get started, would that be true in reverse? For example, would someone who had amassed a lot of Tweet Power have the same kind of transference if they then moved over to Steemit? I'm curious what effect this has on the original economy, in either case.
