I definitely support the blog, I think in terms of content curation and editing, what if posts were done on github, but we used the forum to help determine what gets posted?
We could make a new topic each month and the community could comment with title ideas, drafts, etc. Articles can get both votes and community input on edits so that contributors can submit their PRs with confidence. That gives us quality content, ownership and is totally in keeping with spirit of fostering the Hugo open source community without running as much risk of alienating more non-technical people that might add value.
