Blogs are parallel to research papers in a sense. They're useless without peer review unless you're already intimately familiar with the source material and able to critically evaluate the contents.
So Blogs are more useful when they're aggregated through a site like Reddit, where users have already done the vetting on whether the linked page is valuable. Reddit comments are invaluable to pages by adding additional context. Noting when the content has become dated or inaccurate due to external changes, etc. Sites like Brian Kreb's blog are the exception as the author is well known and respected. But the general blogs? It takes time to earn that community respect.
Then beyond that, how often have you gone on the hunt for something obscure only to run across 3 or more blog pages which look entirely unique, but have the exact same article pasted to them? It isn't that the contents are bad/wrong/inaccurate, but rather who do you trust? How much effort are you going to put in to finding which blog was the original, written by the expert and which ones are bots copying the info?

and ironically enough, if you post your own blog on reddit to be critiqued, there's a good chance it is removed for "self promotion". Funny how that "vetting" works, huh? So you get back to "how do I make my blog discoverable so it can be peer reviewed" and we're at square 1 again.

A lot if it's important. Because as is I already have to do that muckracking on reddit to see who is trying to understand or even read the article and who just wants to soapbox their tangential pet rant. tracing a source back is child's play in comparison.
