It was a pleasure listening! Here's another way of saying what Aggroed did in answer to your question about the amount of Steem being divided amonst the users:

Since the Steem earned can be used not only as a currency but also as Steem Power, the sheer increase in number of eyeballs at Busy/Steemit will make Steem Power that more useful as a promotional mechanism, that can be used for ads or simply for your own blog.

This means that advertisers, bloggers and speculators will be likely to buy more of it and as a consequence drive up the price.
