If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
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.
It seems to me that news streams fall into a few broad categories:
News your friends / coworkers / social contacts want to talk with you about.
News about production opportunities (business, financial, scientific, etc.).
News about consumption opportunities.
General news about the state of the world.
The first group, I find, is adequately served by Facebook. The sort of thing that a friend will bring up in conversation is also the sort of thing that that friend (or a similar friend) will share. (Facebook will also work for the next two, if you have the right friends, but it's still probably worthwhile to do your homework and go deeper than the viral hits.)
The second group is probably best served by a specialized business press, and won't be comparable across industries. For scientists, this is journals that have papers you should be aware of, and it's obvious that scientists should be reading different journals.
The third group is again probably best served by specialized business press, but on the other side--this is subscribing to the marketing newsletters of companies you like, fan blogs of things you like, and so on.
The fourth group is probably worthless, if you view it as the exclusion of the other three. (I don't need to read the New Yorker to find the best of the New Yorker; I can trust my friends will share that, and serve as a filter for me.)
There's another category:
This is not a special case of 1 since by the time everybody's talking about these things it's generally too late to take effective action.
