Hey that has happened to me! I know exactly what you mean. I have been switching to steemitstage.com when it gets really bad, two nights ago it was pretty terrible. I think this must be server load on the front-end.
I do think parameters are important, because most of what happens is automated. But, I think I read timcliff say that it is better to issue SBD type debt when steem is cheap, because we only need to pay back each one with a dollars worth of steem. So if it goes up we can pay it back with less.
I'm not really worried about it, I think 10 percent is still pretty low for such a useful token. But I really like that you are there poking them about it! Debt is a tool, if used right you can avoid hurting yourself.
I agree what you say, we have a much greater responsibility in a decentralized system!
Cheers Glen :)
