The way we do correction here, usually, is a compromise owed to the medium and the needs of most of the learners who write here. In school, the most common way of learning a languag is the well-trodden path of grammar and vocabulary training. Thus most learners need a comprehensive correction and also, often, explanations.

That's what most people do when they talk to children. When the child makes a mistake the grown-up corrects the mistake by mirroring the corrected phrase in their part of the conversation. So, in general, that's not a bad idea. (In fact, that's what I try to do in conversations.)
When you correct someone while speaking with them, the feedback is immediate. Your vis-à-vis can easily compare the things they've just said to your corrected version because it's still on their mind at that moment and it usually is just one single correction. This is also easier on the corrector as they can, for example, wrap their corrections in a question that fits naturally into the conversation.
In writing, like on a message board, that approach has significan drawbacks. In a situation like this, the thoughts of your conversation parther are usually centered around a more abstract level of thinking, they focus on the overall topic rather than the individual sentences. Consequently, they consume the language a bit more passively than they do in a live conversation and are much more likely to miss the correction. Also, since the "chunks" of text are usually longer than just a single thought or sentence, there are more things to correct. If you leave anything uncorrected, chances are that this mistake consolidates. If, on the other hand, you do include every mistake, not only would that leave not much space for any thoughts of your own but also the correctee would have a difficult time comparing the whole of his writing to yours. They might even mistake something for a correction just because you have a different way of expressing yourself.
I could go on, but I hope I've got my point across.
You're never too old to learn something stupid.
Mistake – Suggestion – You sure that's right?
