Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
I think today the norm is providing a short summary of the link target. (If I must click on the link to find out why you linked it, that's almost guaranteed downvote.)
But I could imagine having a "subreddit" consisting of links only, where the norm would be different.
And of course, links to lower-quality articles can still be downvoted.
