Frequently questions ask for the "Best X for Y" but the OP is unaware that "best" is very individual and the criteria for goodness needs to be provided for people to give better answers.
Should "best" be given special treatment when analyzing the question? Perhaps even be considered a stop-word which cannot be used? (at least in the title?)
Try asking, say, "What is best in life?" on Stack Overflow. As soon as you finish entering that title and tab off the entry field, you'll get a little warning:
The question you're asking appears subjective and is likely to be closed.
Pretty much what you're asking for, right? Ah, but that won't appear on Programmers, because Programmers loves subjectivity!
If you see a question that doesn't provide enough information to be answered (not just general, but outright vague) then close it. Otherwise, edit the title to reflect the actual question, assuming it doesn't already. If you can find a way to eliminate "best" while doing so... Well, shucks, that would be best.
Mr. CRT covered the specific issue with adding best as a stop-word, but in general, this is a problem that can't be solved entirely by heuristics.
If we ban "best", "greatest" will take its place. Once "greatest" is banned, "most awesome", and so on will come. Heck, we've even had problems with people inventing words to evade moderation focused on weasel words.
As Mr. CRT alluded to, when you see a question hinged upon a word like that, it's the symptom of a larger problem with the question in general, one that isnt going to be fixed by removing a single word.
