I visit the quant stack exchange site and they try their best to keep the questions to a level that a practicing quant would expect. The math overflow stack exchange is another example of where they try to keep the questions to a higher level. If you keep this in mind then things start to make more sense. As an example consider a stack exchange called Advanced C++. If someone comes in and asks, what does the "class" key mean, then I think it would be more than fair to close that question. Now back to the question at hand. IMHO the question you link to is not a good question. It's not clear what they user is asking. I mean it contains a couple of incorrect statements that people point out in the comments. I'm a practicing quant and I can't make much sense of what the question is asking. If the user is asking in what situations would you do early exercise of an American option then you can easily aruge that this should be closed as its a basic question that isn't up to the standard that a practicing quant would ask. But again, I can't really make sense as to what the user wants to ask. I'm guessing this is why it was closed.
