I think it is one of the the Fastest Gun Of The West strategies. It's better not to delete the post, it might draw some early upvotes getting you on top unless it is truly nonsense, but does guarantee an Enlightened badge if you get enough. You've got 5 minutes to edit what you banged-in quickly into some resemblance of a real answer. More if you quickly delete but then you'll miss out on early upvotes. And downvotes, which I suppose is the point.
I can't really recommend joining that game, a lot of the high rep users that have been around for a year or more are true masters at it and are quite hard to beat. The disappointment I see in the comments from other users that try to get an answer in is rather strong, especially when their answer is just as correct, merely a few minutes late.
This can be quite discouraging. Instead of hunting the 'easy questions', focus on questions that you make you research something so you'll actually learn from the effort. Knowledge gained is worth much more than a rep point.
