Most people on HN appear to be using it for submissions now, which is a welcome development.

All: please submit the original source and then add a link to alt sources in the comments.

I know the twitwall is frustrating (it is to us too) but we want HN posts to link to original sources, and for the site name to the right of the title to reflect that. This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html.

We're happy to pin the alt links to the top of a thread and/or to move them into the top text, as I did in the current case.
