I've seen a recent claim that adding a summary to links is enough of an inconvenience that the links may not be getting posted. I suppose people aren't checking out the media threads for links.
As an experiment, I'm posting this as a place for links. Summaries/excerpts are optional-- please don't downvote links just for not having excerpts/summaries.
I can't see a reason as to why this would be a better place for posting links than the Open Thread.
I think the norm of sweeping everything into the Open Thread has painted the community into a corner. Let's start posting Discussion posts again even if we're not sure it's a good idea.
