Interesting case. You thought 'Copenhagen Suborbitals' itself was news, when the value of the link was in the pictures (everybody already knows they exist). Was intervention really needed, what prompted the change?

It isn't a question of "news". Much of the content that appears on HN has been around for a while. The only newness criterion is that a story not have had significant attention here in the last year or so.
What prompted the change? HN prefers original sources, and stories consisting (nearly) entirely of pictures tend to be treated as lightweight. The site has worked this way for years.
