A related question on automatic diminishing returns for upvoting: Diminishing Returns for Reputation from Upvoting
I am curious if others do the following, and if so, if it is considered desirable behavior:
I see a newly given answer that satisfactorily answers a question. I think, "Fair enough; I think this is the best answer and it was offered in a timely fashion. Surely, it is worth at least my upvote."
Then I quickly see eleven other people upvoting it bringing the total to +12. I then think "Alright, that really wasn't that high quality of an answer -- I regret upvoting it." I am then tempted to remove my upvote as though I should be voting toward some desired reputation bonus rather than simply signaling my approval.
I haven't ever gone through with that, but I wonder if it is considered ideal behavior (for the SO community/service in general) to do so.
Short question A: Should we, as individuals, use the current number of upvotes to dictate whether a question deserves our (additional) upvote?
Short question B: If yes to the former question, should we remove our upvote if within the allotted time in that situation?
Downvoting is not being discussed in any context here.
