I agree with you with my whole heart. If you post something, at least have the pride in your item/ character/ setting/ plot, to check in on it, answer the questions posed about it, and maybe even add little additions to it that you have thought of. If you don't have any pride or commitment with your post, DON'T POST. We don't want just "any old junk", because after giving helpful advice on how to improve it (or just ridiculing it for a while if not worth salvaging), it will just get deleted. We want interesting elements that are worthy of being added to a game, that have enough background and quality that they are the equal of anything in a novel (not house published by WotC or WW), that are presented carefully and clearly so all can enjoy them.
Can I repeat that for the cheap seats? Sure.
If you don't have any pride or commitment with your post, DON'T POST IT
Yes, our standards are high. Most of you can and do meet them. Most gamers have the imagination to create an interesting item, character, and place. If you take the time to do it right, rather than just splatting something up, you can clear the bar. Some of you don't post because you think you are not "worthy enough". Take your time, present your idea, and you will probably find out you are. Even if you fall short, try. Edit the post. Take the advice to heart. Make your post better. If you can strive to meet them, your post will be added to campaigns across the world. Your idea in tens to hundreds of games. Think about it. Is your idea worthy? Now do you see why we are trying to push the envelope on quality of posts?
Now I know, there has been a great deal of "hit and run" posting, as someone splashes something up, then never checks the site again. Some of this is attention span, other parts are people realizing this is not the site they thought it was. A scant number of the "hit and runs" are worthy, the rest are a waste of memory space. Many of the inane items, settings, and characters are quietly deleted a few weeks down the line.
