I agree, the substance was there, but the story could use some editing and organization. If it were me, it'd look something like:
1) How people think URLs work, the good parts that people see every day
2) Abstract problems with URLs, followed by concrete examples, maybe links to prominent related bugs
3) Suggested fixes for the problems, including what browers are doing at a UX level
4) Honest look at tradeoffs involved for end users
5) Remaining complications and unanswered questions
