Can't say I'm surprised by the overwhelming lack of response on the grammar question which currently has a bounty of 50 points. Only @Andrew posted an answer and was repaid by an anonymous downvote.
I get that it's not a "fun" question or one that really picks your brains, but it is clear, and above all, specific. The opportunity to write a good solid answer covering the four different constructions; Present Simple, Be + Going To + Verb; Present Continuous, and Pure Future, has been presented on a platter.
At least once a week, ELL receives questions asking about the usage or the difference between two or more future "tenses", yet many users with the talent and know-how, tend to avoid answering them. I think I can guess why, the instances where two or more constructions can be interchangeable are many, and explaining why one form is preferable to another inevitably leads (less confident) users in a rabbit hole that seems to come out in China.
The reason for offering a bounty was to obtain one or more "great" answers which would cover that particular usage. We would then direct newcomers asking very similar questions to that post, and/or close their questions as being duplicates.
In any case, I would like to ask the community, most humbly, why they shun bounties in general. They don't seem to be hugely successful, even ones that offer 200+ rep.
Before anyone asks, I have tried my hand at answering those type of questions but it's rare I cross the 1+ barrier, does the low vote mean the answer is meh? Do users feel I have omitted fundamental aspects (see: rabbit hole syndrome)? Anyway, I'm not the best man for this job, there are others who are better at being concise and accurate than I am.
So, whats up?
