Due to a rash of "yours sucks" projects and comments, I've taken it upon myself to create a project that defines ettiquette and, once more, points out the ToS. And, yes, i know this project sucks! sucks the soul right outta me to do it.
Step 2: Consider yourself.
Ego is a good and necessary thing, in moderation. Try to put yours aside while creating a project and just concentrate on teaching/amusing/creating. If you're improving on an idea, constructively explain how/why you are improving it, and then go on to do so.
Step 3: Don't be afraid!
Your opinion IS VALUED! If people don't get feedback, they don't improve, things stagnate, and we end up like...well, the rest of "them", the docile placated masses that have freezers full of t.v. dinners and still buy kitchen gadgets off t.v. because they "make life easier". If you think something's great, go ahead and rave, if you think something's not so hot, say why and try to help it become something useful. Please don't just say "that sucks" or "that's useless". It doesn't help and leads to flame wars. Yes, one of man's greatest skills is our ability to create fire, but one of our greatest faults is the ability to create war, so please don't mix the two.
