we should introduce content-type

our key metric should be how much time people spent on Steemit.

we should think about introducing downvoting as normal way of saying "this is not good for Steemit".

All interesting proposals. Thank you for writing this. The TIME SPENT and the ATTENTION PAID, is the KEY indeed! This is our currency in life, the real basic economy of human living, before there was even money. Our time, and what we pay attention to, is at the base of our whole lives.

What's more accurate measure of someone's valuation is there than the amount of time and attention they are willing invest in content. If you're willing to spend your valuable, previous, limited time on something for longer a duration than something else, it means you must value it more.
