I've been pretty active lately on StackOverflow, a question-and-answer site where people ask "what does this error message mean and I how can I make it go away?" for a variety of languages, platforms, and business purposes. There are a number of brilliant features on StackOverflow including voting on both questions and answers, and closing questions that are off topic for the site. This means less junk to wade through and a bit more confidence that any particular answer is actually going to be helpful.
One of the reasons questions get closed on StackOverflow is because they don't have an answer. There's a category of nasty questions of the form "Have you stopped [bad thing] yet?" that have no answer. If you never [bad thing]'ed in your life, then you obviously haven't stopped. Yet answering "no" implies you continue to [bad thing]. Answering "yes" implies you [bad thing]'ed for some time, but have no stopped. Either way, it's bad. So I knew the question "Should
LINQ be avoided because it's slow?" was going to be closed. And sure enough, it was. But not before some really excellent answers and comments accrued to it. Like these:
Slow is irrelevant to your customers, your management and your
stakeholders. Not fast enough is extremely relevant. Never measure how
fast something is; that tells you nothing that you can use to base a
business decision on. Measure how close to being acceptable to the
customer it is. If it is acceptable then stop spending money on making it
faster; it's already good enough.
