It can be an indicator of credibility. There are lots of factors that do into credibility of reporting. Because anyone can post whatever they want on social media, there is more of an emphasis on understating how credible the report/opinion is. If I post here, does that make me more or less credible than if I post on twitter or youtube and have 500 people who follow me? Ultimately, it's the same guy and doesn't constitute actual reporting. There are lots of things that factor into how credible I feel reports/posts are. Does the person get paid to report? Who is paying them? Do they have access? How focused are they on the Cardinals? Are they reporting information/observations or speculation/takes?
My opinion on the matter.
