I tried to get a rather interesting question answered yesterday, What is the value proposition of commercial databases like Microsoft SQL Server, DB2 and Oracle? Sadly, the question was swiftly closed. Four of the close votes came from users heavily involved with one of the mentioned commercial products.
I'm not trying to start a flamewar here. This information is not readily available anywhere. If I need to take a decision on which of these products to use, there seems only to be marketing materials to go on.
So, is there a way a question like this can be protected? I'm pretty sure I'm not the only one who would like to see some hard data or real experience brought into a question like this, but the vote-to-close model is heavily tipped in favour of closing questions not liked by a certain group, and getting it reopened is almost impossible, since you have to know the specific URL to find the question and reopen it.
