Bloggers have no such worry. In today's time, if a blogger hits better than 50% of his or her predictions, they become legitimate, and they have very little to lose by going all in on some informed speculation. But if an official journalist misses once, their credibility takes a hit.
And that's what makes bloggers a viable part of the information cycle. But at the end of the day, traditional journalism will prevail. Individual bloggers will break a big story here or there, and bloggers collectively may break most of the big stories. But, at the end of the day, much of what bloggers write (with the exception of some of the big ones, like Clay Travis or Brooks Melchior) is still totally reliant on what is reported by the traditional sources. Bloggers don't have the resources to provide the consistent and in-depth coverage of a team like the traditional journalism sites.
