What annoys me most, besides, all the crying for help, is asking for help without telling the helpers whether the help was useful.
What I find most annoying (here, and on other forums, too), is when someone asks for help (and describes the problem in detail), and then someone posts to say they'll help them, then a final post by the OP stating "thank you for the help" or "I got it to work - thank you!" - without ever stating what they did to fix the problem, or what the help is that they received to fix the problem!
I find this scenario often when I am searching for help on a variety of issues - hardware, software, PC/OS configuration, etc. Its so annoying! If they would only take a small amount of time to post what they did to fix the issue, they could help so many more people, and contribute back to this great time waster we call the internet...
