The best way for the site to grow is probably by creating more original content, and also by addressing graphic design problems that people google about.
I was trying to think of questions that I would anctually enjoy answering, too, questions that would make me think creatively and come up with new information. No point in creating a bunch of adobe how-tos, we already have plenty of those.
Ok, these are some of the ones I came up with. They are not very creative, really, but it's a start. I don't mind being the only one asking, but if you think they could work / contribute to the site, please feel free to grab any of these and post it.
EDIT: Taking Aarthi's fantastic feedback in consideration, edited questions and marked those already asked (in case you want to grab another one!).
What should I consider when buying a laptop as a graphic designer?
What are hardware / technology requirements for designers that are just starting?
How do I calibrate my monitor to have 'real colors' / how to see 'real colors'?
Being a designer
How do I transition from digital to print design? / How I transition from one design medium to another effectively?
What’s the difference between an art director and a creative director?
How can I keep up with design trends? / How do I keep my design work from looking old-fashioned or outmoded too soon?
Can personal projects help start a career in Graphic Design?
What are the challenges of working as a (insert specialisation) designer?
How can I get my Graphic Design students more motivated?
(New) How do I teach students modern techniques without them losing sight of fundamentals of design?
Working with designers (not being one)
(note: Only to be phrased in relationship with design)
How do we go about arranging an internship for a graphic design student?
What questions should I ask a (...) designer for a (...) position?
I think there are two areas we haven't really touched yet: Teaching design, and working with designers while not being one. We have lots of people coming from development, but there must people wondering about these other things too.
Are these questions you'd find appealing to answer? Some of them look quite broad, and they could be answered in other sites like workspace, but if we focus our answers in GD they could be good.
What do you think?
