This is the question I am referring to:
I suspect that this question was closed because it was an unpopular suggestion. Whilst I agree that the suggestion is flawed, I don't see any problems with the question as it stands, and can't think of any valid reason for it to be closed.
As well as the fact that the question $\textit{was}$ closed, from what I can see, no-one that voted to close left any comment indicating why they were doing so. Considering that several questions have been posted in meta recently asking people to leave comments when closing a question, I was surprised to see this, because if I can't see a valid reason for closure, I doubt that the OP can, which may lead them to suspect that the question was closed because it was unpopular. Whether or not this is true, I imagine that it would be fairly discouraging for a new user.
