Great question.
For me, NPR is a good source. CNN, ABC, Washington Post, NY Times, Politico, main media sources who for the most part have been around a long time and who's reputation is built around solid reporting. Also fact checking sites. If you don't like these sources, its not hard to check on stories that come from other sites, even if the story seems pretty wild. Maybe true, maybe not. How to tell?
Fake Or Real? How To Self-Check The News And Get The Facts

a small excerpt:
Look at the quotes in a story
Or rather, look at the lack of quotes. Most publications have multiple sources in each story who are professionals and have expertise in the fields they talk about. If it's a serious or controversial issue there are more likely to be quotes — and lots of them. Look for professors or other academics who can speak to the research they've done. And if they are talking about research, look up those studies.
Look at who said them
Then, see who said the quotes, and what they said. Are they a reputable source with a title that you can verify through a quick Google search? Say you're looking at a story and it says President Obama said he wanted to take everyone's guns away. And then there's a quote. Obama is an official who has almost everything he says recorded and archived. There are transcripts for pretty much any address or speech he has given. Google those quotes. See what the speech was about, who he was addressing and when it happened. Even if he did an exclusive interview with a publication, that same quote will be referenced in other stories, saying he said it while talking to the original publication.
I find right wingers to be most extravagant in the area of fake news. Anything from
@Flaming Pie or any "new member" with a handful of posts should be automatically put in that category. This is a quote from a guy who runs a fake news business:
When did you notice that fake news does best with Trump supporters?
Well, this isn't just a Trump-supporter problem. This is a right-wing issue. Sarah Palin's famous blasting of the lamestream media is kind of record and testament to the rise of these kinds of people. The post-fact era is what I would refer to it as. This isn't something that started with Trump. This is something that's been in the works for a while. His whole campaign was this thing of discrediting mainstream media sources, which is one of those dog whistles to his supporters. When we were coming up with headlines it's always kind of about the red meat. Trump really got into the red meat. He knew who his base was. He knew how to feed them a constant diet of this red meat.
We've tried to do similar things to liberals. It just has never worked, it never takes off. You'll get debunked within the first two comments and then the whole thing just kind of fizzles out.

As you can see, I try to post links with stories and information that I post here. Its completely reasonable to ask for a link when another poster makes some strong and maybe wild claims. Links from weird sites aren't necessarily bad, but it pays to look at the "about us" section and if really curious about a story, do a search on the author's name to see what else they've been posting or to look up background information on them.
Of course, who wants to put a lot of work into looking up the background of a story only to find that it is bogus? And so, going by the common sense rule, if it looks strange and weird, it probably is. Personally, I never fact checked the "pizza gate" story until recently. I first saw it coming from Pie, it was really weird and so rejected it out of hand. Turned out it was fake. Not surprised.
One thing that I'd appreciate: if you think a story is fake, say so.
And sometimes the fake story is a story in itself. Like the one I got from a poster on RIU about Plasma Beings.
