I gave you an upvote for thinking about improving things, but I will now wholeheartedly disagree with your stated mission of how to improve them. It sounds like a good idea on the surface, but I'm convinced by experience that it is not so good.
As I read your node, I see mostly knocks against Perlmonks and the people you'd pull away from Perlmonks:
- new users' questions aren't welcome at Perlmonks
- Perlmonks is not an understanding nor welcoming environment
- new users couldn't ask interesting questions, and couldn't answer them among themselves if they did
- the PM servers and admin team aren't providing sufficient resources
- a WYSIWYG visual layout interface that requires a mouse and a keyboard is more productive when producing a text-only node than what PM provides
I'll start down your list.
- If only newbies are on your site, who answers questions?
- What's unwelcoming about the PM environment? What's unwelcoming about it specifically for newbies? What have you done to improve this situation? If you don't know how to improve it, how would you do better on a new site?
- If higher-level stuff is here and lower-level stuff is there, then what do you do for the newbies leading newbies who confuse things and drive people away from the language altogether? Basic questions about the language can still be fundamental, and new users or Perl or PM aren't necessarily asking basic questions.
- PM is running more smoothly right now than it was a few months ago. By splitting the site, you'd make each portion less likely to get resources than the combined whole. If you could bring a second server and a second set of bandwidth to PM users, why not to PM itself if you're worried about the strain?
I think your heart is in the right place, but I would strongly discourage trying to help PM or potential users of PM in this manner. I think your efforts would backfire on both counts.
