Although the description of webapps.stackexchange.com specifies that its for:
power users of web applications
it really does a great job in being the place where people go when they have extremely basic questions about web applications, like 'How to change Facebook username?', to some fairly complex questions like 'How do I download subtitles from a YouTube video?'
Personally I have not used it so far however I can potentially see myself and others (who haven't as yet) make great use of it.
There is just one issue I see about it, and that is the naming, we are in a world where popular services like YouTube has both a web application and a mobile application, terminology wise since these services do have a web backend (http/https) they both could still be termed as web applications. However even to amateur developers and journalists it would seem as 2 different terms, google returns more than 2.1 million hits for 'difference between web app and native app'. Tomorrow when wearable technologies like Google Glass and the future Samsung and Apple smart watches gather popularity, applications on them would probably be termed as 'google glass application' and 'smart watch application' respectively. Users should not have to think twice before using a great and resourceful site like webapps.stackexchange.com
just because there is a confusion of terminologies, terminologies which aren't in the hands of developers but instead of the media and the public as a whole. Ask some of your non computer science educated friends the difference between 'world wide web' and 'internet' and you'd be surprised to find out how many of them can actually distinguish the two.
Having a more generic name of applications or apps would reduce the confusion created with the current name of webapps. Although these names too have their cons.
What do you think of this issue? If you are adept with computer science please think of it in the perspective of someone who wants to change their password on one of their iPad apps as opposed to the user of stackoverflow.com in which case would be an amateur/seasoned developer.
