I was having stability problems with Steemit for a few days, too. Seems like things have stabilized more recently.

I have a lot of problems with the Microsoft Edge Browser Working.
Yet, this is a browser that allows for better, easier writing when the browser works.

I'm not a fan of Edge. It always feels bloated and slow on my computer, though I have to use it at work. Same with Chrome. At home, I use Brave almost exclusively. It seems a good bit zippier to me.

What to say? If only 284M Steem is available to trade, why burn?

This is a really good point. I'm not opposed to burning, obviously, but we have to be realistic about what it can accomplish. What we really need is to move lots of STEEM from the exchanges (redfish & plankton) into SP that's held by (new) minnows and dolphins. Burning and club#### participation don't help much with that. As long as ~79% of all SP is held by 323 Orcas and above, the "crab bucket" concept from the Steem whitepaper is fundamentally impossible.

create a browser solely for Steemit. Years ago I made an IE 4 browser considered to be the most secure.

Certainly possible. It doesn't even really have to be a browser. It would just need to be a desktop application that interfaces with the Steem APIs. I think it would be a full-time job, though. Personally, I wouldn't be able to accomplish it as a "side project".
