I'm interested in fragmentation. Reddit has it, and Stack Overflow has it too. I have no idea how they'll fix it.
If you want to ask a question you need to ask the right SE site. Some are obvious, but others have overlapping sites and it's confusing for the target audience.
What's worse is that some of these sites have made agreements with each other to funnel the "wrong questions" to the right site - that's great, but a bit confusing; while others have just decided independently that some particular style of question is "off topic" and they'll shunt you off to another site, and that other site will close your question.
I love SE, but I understand the frustration that some people have with it.
They have the Main sites, and the Meta sites, and the chat stuff. I think they could also have a branch off "discussion site". Any questions deemed as wrong questions go to that discussion site. You re-brand it, so as not to dilute the strict question only format of the main sites.
And, for all the "META IS DEATH" (true) sentiment there's a heck of a lot of meta going on over there.
But I do like SE.
