>where users have already done the vetting on whether the linked page is valuable.

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.

>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?

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.
