The answer is (almost) always YES! - AKA Kiteman's Law Answered
There is a fairly regular kind of thread that appears here.
It starts should I make an Instructable about insert topic here?
You know what? The answer is yes. Even if nobody else on the site is even vaguely interested in insert topic here, it is probable that somebody with access to the internet, somewhere in the world, will eventually develop an interest in insert topic here and resort to Google. Since this site is googlable (is that a word?), they can end up here, grateful to you and potentially a new and useful member of the site.
So, unless it breaks the guidelines for what is suitable here (basically, Please remember that this is a family site), and you're not just re-inventing the wheel, then the answer to should I? is always yes.
