This is probably something a lot of you have already thought about, but it doesn't seem to have been addressed here on meta (or I didn't manage to find the post).
A lot of topics, problems and solutions about vi/vim already exist scattered around the various sites of the stackexchange network, mostly on [stackoverflow], [superuser], [unix.se].
What are the policies on asking questions which already have answers on other SE sites? Would it be ok to answer such a question linking to the various related questions on the other sites and summing up the conclusions they reached?
Here is a practical example of what I mean: I was wondering today why backspace in insert mode does not delete the previous character as usual. This (very common I imagine) problem does not seem to have been addressed here on Vi.SE, but a little research led to
- Backspace key not working in Vim/vi on SO
- vim not allowing backspace on SO
- Vim backspace key only works on new text on SO
- Backspacing with vim on SU
- Backspace key not working in vim on SU
Also I won't mention a few posts on Unix.SE on related problems more terminal-oriented, and of course external resources like vim.wikia.com, and so on and so forth. I think you got the point.
So clearly questions like these have already easily retrieved solutions scattered around. Would nonetheless be useful to address them on this site? This could make sense to me as a way to better organize information that while already existing is scattered to the four winds, making Vi.SE a central hub for information about a specialized topic. What do you think?
