I really like the layout and think this would be super helpful. Obviously it will provide more value once the community grows and their are more upvotes. So far all the categories I looked at all had 0 votes.
One thing you may want to try out in the early days to make it look like there is more activity is to create a bunch of different logins for yourself and friends. Reddit had a super admin tool that allowed them to select from a "user" dropdown anytime the founders wanted to post a comment. That way it appeared there was a lot more dialog and activity.
A grounded understanding of media theory and media history is the best way to grasp good design.
This can be obtained by looking at the story of media back to the Gutenberg printing press. Look through historical documents, old magazines, brochures, etc. and ask "why did they do it this way?" This gives you a plethora of reasoning and inspiration that you can pull from and reapply throughout your career.
Web design is mutable and loose. Graphic design software is very distant from users and reason. Without grounded thought, your software will do muh of the design for you. The result will be inconsistent and inferior to design with classical uderstanding.
Look to western art history back to the Gutenberg printing press at least. Get more particular in the 20th century and hunker down on Bauhaus influence and mid-century advertising. Learn about Engelbart and hypertext theory and any associated interests of yours.
I find more and more that actual good designers know where their designs come from and reference that understanding in their application of them.
Way too much chrome, little signaling as to "is this interesting?", or "is this bullsh1t?"
Not enough content for search to be useful. The other day I was thinking "Text overlaid on a video uses glow, shadow, and similar effects to overcome a variable and imperfectly controlled background. How do I do that in photoshop?"
It turns out to be easy to do (just a setting on the text layer), and I just want to do it and get back to work. I don't want to see seven different ways to do it. I don't want to see somebody demonstrate the wrong way to do and ask for help fixing it (eg. Stackoverflow)
