In response to this question: Why are suggested edit votes limited?
Raise the suggested edit vote limit. Currently it is at 30 per day. I would suggest 60, but any number above 30 would help.
Advantage: More users could vote on suggested edits. This would allow edits to be approved faster and keep the queue of suggested edits low.
Disadvantage: Expands the potential for abuse.
In my opinion the potential abuse of a 10k user propping up a sockpuppet with peer edits is much smaller than the benefits of allow more users to peer review.
Edit: An example. I noticed this suggested edit and that it had already been approved once. It really needed to be rejected, however, I was out of votes. I posted it on meta's chat and two people responded to reject it. If I could have rejected it myself, I don't think I would be as concerned and would have needed to ask others to reject it.
