I remember a lot of Steem Witnesses telling about steps that need to be taken to support the peg and mistakes that were in the history of Steem, and pushing for steps that support the peg.

There is a problem in that Golos isn't as liquid on the markets as it should be, and without such liquidity the GBG isn't as viable, but we (delegates of Golos and Golos Team) working on improving the situation. Unfortunately the best way to do it is to give it time.

You are a little too optimistic on Golos/GBG, but with that thing you are launching there, it gives me a bit more optimism as well. :-)

To keep abreast about the things happening with Golos you can watch (and perhaps participate?) in weekly English editions of Vecher with Golos, that alternately happen on Wednesdays/Fridays 20:00 UTC+3 (thats Moscow Time) on Google Hangouts/Youtube.
I tend to write posts with them after the hanghout.

Here is probably one of the best editions, and thats the one where we talked about the peg, and steps to support it.
