In trying to help a proposal I support get through the "discuss" phase, the following vote-allocation strategy seems to work if your goal is to help the project get to commit and beta as quickly as possible:
- In the early stages of the proposal, just vote for whatever you like.
- As some questions get close to acceptance (20 votes, apparently), move your votes to those questions to put them over the top, assuming that you don't actually hate those questions.
- When an accepted question has a comfortable margin (~25 votes), move your votes to other questions which are nearing acceptance.
This strategy is possible because there doesn't seem to be a limit on the number of times you can change your votes, and because there are usually more than five questions that you would vote for if you could. In fact, low vote limit + unlimited changes actively encourages you to strategically change your votes often.
Do the Powers What Be consider this abusive? What about the community? Do others have similar strategies?
