I'll admit - I'm beginning to have a real bias against "questions" that don't end in a question mark.
Two recent examples:
What is the scriptural basis for "Love God and do whatever you please"? (Currently "Love God and do as you please")
What are "all things" in "Let all things be tested, keep to what is good"? (Currently "Let all things be tested...")
In both cases, there is a good question hidden in there, but it seems really, really easy to have it denigrate into a "What do you think?" as opposed to an answerable question.
What I'm wondering is this - Is this an actual iron clad rule, or just a strong correlation? In other words, can someone come up with a declarative post title that actually makes for a good answerable question?
