With the vast number of proposals that are up that don't have links for discussing them available, it appears that many users of the voting system have never taken a look at this forum and are quick to make proposals without bothering with preparing a discussion topic for it. I would like to see a link to Feature Suggestions put up at the Voting Tool's homepage to encourage posting a topic first.
I would also like to see some mechanism in place for users to add a discussion link to a proposition, to those that had been hastily written, to allow supporters and naysayers to offer more useful feedback than simply votes.
EDIT: I had posted this in the Voting Tool as Proposition 653.
