Looking at titles on the Newest Questions page today, I'm not seeing many questions:
"I have two top panels in Ubuntu for some reason"
"Performance Test Software"
"Feedback for 11.10"
"Intel 3945ABG wifi sees only some networks"
"Cannot modify my USB Files/Folders"
"Kmail migration issues in 11.10"
"Broadcom 4313 (gn) wirelless card on HP Pavilion g6 weak signal but close to AP"
"Network Manager Failing to allow Ubuntu 11.10 to shut down."
"aptitude update as cronjob, customize the cron-mail-output"
People are not starting their titles with interrogatives and ending them with question marks. While this may seem like a trivial issue, in my view we are losing the battle to get people to ask coherent questions in AskUbuntu.
A question is a useful mental constraint. It forces people to pinpoint exactly what they want answered, and cut out side-issues. It's also a useful condensation: it makes it easy for question-answerers to scan for problems they might be able to solve. Finally, the presence of non-questions on AskUbuntu prevents visitors from realizing this is a Q&A site, not a forum.
... and display a notification if there's no match?
Hey, that doesn't look like a question
AskUbuntu is a Q&A site, so we recommend you phrase your problem as a concrete and answerable question. For example, don't type:
How do I install software?
