Decision making is not the goal of this site, it is only a way to see various pros and cons of various devs on various proposals in a single place.
This is for the community to have a coherent view about what you are talking about now spread into reddit/mailing/forums.
If you did not analyzed a proposal yet, you don't have to fill out your opinion veto or approval.
It is only to show what you would you "approve" and what you would "veto", after your analysis.
Then point out all the discussions in the opinion section that lead you to your conclusion.
You can change edit your position as you progress into your analysis and as new BIP get redacted.
I'm eager to include the new proposals.
