The current placeholder text in the "Ask Question" form title reads:
What's your web applications question? Be specific.
I think this can be clarified to (maybe) stop or slow down users who are new to the site and have the mistaken idea that the site is for web application development questions.
Perhaps it could be changed to something like:
What's your web applications utilization question? Be specific.
(h/t Ramon Melo)
What's your question about using a web application? Be specific.
What's your web applications usage (not programming) question? Be specific.
I think something (anything!) that does a bit more to emphasize that the site is not for programming questions would be useful.
