- Speeds up the tag synonym voting process.
- Easier to locate (as opposed to navigating to each individual tag wiki page).
- Encourages users to vote on more than one at a time.
- Serial up/downvoting. But this really isn't even an issue because, (1) only experienced users can vote on tag synonyms, and (2) more than one vote is required to approve a tag synonym, so the occasional serial up/downvoter won't significantly impact the overall process.
