I tried to get a rather interesting question answered yesterday, https://stackoverflow.com/questions/8439030/what-is-the-value-proposition-of-commercial-databases-like-microsoft-sql-server 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.
