Well, I definitely understood "I publish an unbiased price feed".

just FYI, it doesn't mean what one would think it would mean just from plain english. Steemit witnesses publish a price feed and some witnesses publish one thats exactly what the market rate for steem is. Some increase or decrease the price feed from the actual rate (which has an effect on, among other things, how many steem you get when you convert steem dollars)

actually the only thing I'm still unclear on is blocks. It's time to buckle down and get a handle on that.

A block is a list of transactions on the steem blockchain (or any blockchain really). Think of it like a page in a ledger (or, i fyou still remember when people used to balance their checkbooks, like a page in a checkbook). Blocks are produced (on steem) by witnesses running nodes.

Block size is how large that block can be -- literally how large the page in our accounts ledger is. The advantage to larger blocks is that if blocks are too small, each block might not be able to contain all the transactions people have submitted (this, btw, is a huge issue in btc right now). The page in our ledger might be filled, and the guy who wants to make a new transaction will have to wait and have it included in a future page.

the disadvantage to larger blocks is that as blocksize increases, the computer power necessary to run a node also increases. So increasing blocksize has the advantage of making transactions quicker, but does so at the cost of making it harder to run the nodes which produce the blocks.

so when aus says "Bandwidth issues have subsided, I see no reason to raise this for now." basically hes saying that out blocks are large enough right now to quickly proccess the transactions that people are submitting.

(side note, on steem, transactions are not just moving money... they are posting, voting, pretty much anything you do, though in other chains like btc are generally just simple ledger transactions)
