"Hidden features" is a series of poll "questions", without being answerable questions in the sense that Super User is a Q&A site, that started on SO and is now largely discouraged. Due to popularity, older "hidden features" questions are kept, even though they make poor questions, though I believe they should probably be closed and locked to avoid copycats.
Also see the comment on your question:
poll-style questions like this are discouraged; they are better suited to discussion forums. Super User is designed for more concrete questions. a question like superuser.com/questions/149055/… is a bit more palatable because it's restricted to the uses of a single program. as @hotei's answer points out, none of your own examples are particularly "hidden features" of Ubuntu.
But I hope everyone changes their minds, because I just posted 50 "hidden features" questions on Super User:
- Hidden features of Edubuntu 10.04 LTS
- Hidden features of Windows for Workgroups 3.11
- Hidden features of Vim
- Hidden features of Emacs
- Hidden features of Geany
- Hidden features of Google Chrome
- Hidden features of Opera
- Hidden features of Firefox
- Hidden features of Mosaic
- Hidden features of XChat
- Hidden features of Screen
- Hidden features of Less
- Hidden features of Sed
- Hidden features of Ed
- Hidden features of the Magnetic Needle
- Hidden features of Butterflys
- Hidden features of parsing HTML with regex
- Hidden features of insanity
- Hidden features of pharmacology drug abuse
- Hidden features of god, where does it end?
I can only answer for my vote.
The secrets you had as example was so very basic (how tab completion works and how to copy/paste in a terminal). I could not on that basic take your question serious and felt that it had no merit being on SU.
I would say that Ubuntu is at same time too wide and not enough.
When asking about hidden features for Ubuntu, you will end with answers matching to Linux in general, or particular programs used by this or that distribution. So it's too narrow, because it should extend to whole Linux, and at same time too wide, because extending to plenty of pieces of software you can identify.
When asking about "hidden features of Vista", you can't single out really parts of it. By its nature, it's a monolith: the desktop manager, the file manager, everything is included in this monolith.
As opposed to Linux, where the desktop manager is not only used by different distributions, but as well changeable for the same distribution. Same for most of parts. It's hard to give a list of "hidden features", for a system on which you can potentially change all of its parts.
As quack quixote mentioned in the comments to your question, "poll" questions are discouraged from the trilogy sites because there is no solid "correct" answer, people just vote for the ones they like the most. Unfortunately for you, you picked a topic that was less favourable to the community browsing the site at the time you posted it, hence the quick close and down votes.
FYI, If you look at the revisions for the Windows Vista question, you'll see that it was "locked" and "unlocked" several times over.
In addition to Andy's response, and this is just a hunch, here are a couple of other thoughts on this:
- The Vista question was asked about a year ago when things were still settling down after SU was launched. Could be that the community attitude toward these types of questions has shifted since. The locking activity that Andy mentions could be an indication of this.
- The Vista question had a bounty set on it (indicated by the gold border around the accepted check mark). Bounty questions can't be closed or deleted during the bounty period (short of mod interaction). May be that people decided to bypass it during the bounty period and then never came back to it. The bounty was set on it a couple of months after the question was asked, so maybe it was set to prevent it from being closed. I've seen that strategy used before with varying success.
Many of the
Hidden Features question brings out hidden gems and hence adds good view value to it.
Check for example the Hidden Features of HTML.
I have been working in HTML since 1998. Still I had no idea about the first 3 answered features.
I am willing to bet that most of you did not know at least one of them, please comment honestly!
