For a slightly different take on this, compare it to general web hyperlinks.
If I create a web site, I can include links to anything & everything: Google, articles in major newspapers, government web sites, blogs, Stack Exchange questions, etc. Nobody can do anything about it, and it doesn't really matter! If I link to the New York Times does that mean that I have anything to do with the New York Times? No. Does it mean that the New York Times trusts me? Absolutely not. All it means is that I find the New York Times to be a useful place to visit for some reason. Perhaps I agree with their editorial opinions, or perhaps I disagree. Or I may just like their focus on New York City. Or whatever.
However, if I am perceived as an expert then my link means something. Not a lot, but something.
This is in fact one of the key issues with Search Engine Optimization. If I link to 1,000 other places, then my web site isn't any better or worse (well, could be worse if I am perceived as a link farm). Those 1,000 places don't get any benefit or harm from my link, since it is something beyond their control. But if I am an "expert" (e.g., a major well-regarded subject matter web site) then my link to you will count for "something". Enough "somethings" and search engines will figure out that maybe, just maybe your website is itself meaningful because of all the "experts" that point to it. But the arbitrary web sites (hey, read my Facebook page, I visited xyz web site!) won't affect that search engine ranking in any significant way.
Back to Academia. There are much more definite rules for how/when citations should be used in scholarly papers than hyperlinks in blogs (which have no rules at all). But you could have journal citations that reference something useful (prior relevant research), something reasonably interesting (similar fields) or something seemingly irrelevant. Unless the article that includes the citation is itself from a top author or (due perhaps to relation to current events) the article becomes widely cited in general (non-scientific) media, it doesn't matter.
