If you add more to your list I might contribute to it.
I briefly checked your list and in the distro list you are missing of the important new ones - Solus. :)
EDIT: I don't think you need to have huge screenshots everywhere (personally I rather have text info than graphics) and it's not super useful anyway to show screenshots since it does not tell you much about anything at all. Feature lists, as in bullet points, would rather get my preference.

Can't disagree with you on that. I remember seeing a couple of repos recently that have like a "More" button which actually loads the image. Will try tracking them down to see the code and using the same procedure.
I heavily moderate it. Most of what's on that list has been verified by me. Contains about 50 pieces of software. The problem is: people don't give a shit about this heavily curated lists. They just want a gigantic list of every software ever. Heck, I think I have like five commits in total in that section, but at least it satisfies one of your criteria (GNOME or KDE based or something else). No KDE user ever has stumbled upon my list and made some contributions, so I'm really lacking on that front.
I'll see what I can do about the rest of your proposals. I'm pretty sure I could easily implement at least half of them.
