Over time, Wikipedians come to appreciate the amount of time the development and network operations teams put into keeping the site running as well as possible.
In addition to learning this, another vital rule is picked up fairly early on in the learning process:
Don't give the developers ideas.
One minute you're joking about pwnage and running vandal bots. Next, you're getting 403 errors from all the sites. You discover that a network operator has blacklisted your entire ISP with a well-placed line in the Squid configuration. Who's pwned now?
Taste varies. Don't ever let the developers get the impression you're not totally satisfied with the quality of the skins in MediaWiki. All hell can break loose when CSS goes wild.
You say: Man, Vector needs an overhaul.
They hear: We want pink ponies!
Picture it. No, it's not pretty, is it?
WONTFIX is a bitch. So is life. Get used to both, and don't revert the former. Actually, don't revert the latter, either.
Just don't go there. Asking for stuff to be deleted is a real minefield. You're liable to end up responsible for half the Wikimedia wikis being dissolved or something. Ever seen 48,004,333 pissy Anglophones wander up after their featured articles have gone walkabout? You don't want to. It gets messy.
You say: Developer, can you please delete [article]?
They hear: Can you please nuke the German Wikipedia?
Ask them to make a simple template for true false statements, a module was created. Ask them to make Wikipedia slightly more responsive for mobile users, they make an app and an entirely different skin for it. Ask them to make a bot that fixes a specific set of typos, now it is hosted on Toolforge and fixes all known misspellings in the English language.
Heck, give them a coffeepot and then they would make an internet protocol for it.
That's just it, don't reinvent the wheel. You have a cool idea, you imagine it would help the many, feed the starving and enrichen the abundant, you create it with all your available time, with all the wit and grit, you stay at the computer for so long, you finally publish it. But there is one unfortunate thing, it's already created.
