Ryan writes "I'd like to encourage more diverse questions." but what Ryan likes (sorry, please do not take it personally) is not important at all. Please respect every user and his or her needs. People like Stackexchange, so they come. Then one day they discover there is "Graphic Design" too, great! So they post their questions according to their needs. They do not make up questions or come here to please the veteran users but to get their problems solved. Encouragement means solving the real problems of real users, not having an amazing website which Ryan likes better.
Then I read: "Software support are not on topic, for 2D, 3D, animation or anything else."
You cannot easily get inspiration or creative ideas from a website, even one like this with competent peers. And having other users "do your work" is also frowned upon here.
But "software support" is for me a classic reason to get here for receiving or giving help. Because first I get creative but then I have to realize my ideas -
and that is where most users need help.
Here is an example: Need a font size with fraction in Inkscape
I had an idea for some decoration and I had it all worked-out and almost finished and just got stuck with one not-obvious tiny technical detail. You can tag that software-support and delete it. But it was saving an idea I had almost realized/finished and which is now on the cover-page of an entire booklet-series and which our local readers so far find pretty.
From my experience with Stackexchange and several Wikipedias and Wictionaries: If you really want to ENCOURAGE anything, please do less deleting, less rules, less user-police. I do not believe that your servers or your disk-space are any problem. But any time you frustrate a (new) user about some rules or other crap, you have lost a lot of potential great ideas and answers for later. Bad questions without many votes nor answers automatically sink to the bottom of search-results I believe.
On OpenStreeMap there is one battle-cry by the real heros: Don't talk about it - get out and map! So here that would be: Less Meta, write more wonderful answers even for (new) users who are less competent than you are. That would be encouraging.
