Ah yes, information overload, a problem that's at least 75 years old - a problem that was partly attempted to be solved by Time magazine with it's creation in 1923 by Briton Hadden and Henry Luce as the first US weekly magazine. Not that I was around at the time!
Leave it to Seth to catch our attention, eh? Another virus has been sneezed! Yeesh, he's good at that...
There are so many facets to this problem, but I'll just confine it to two points, well, with a bit of wiggle room.
The front-end of content creation has exploded on us, with the ability to create and distribute widely and at will at a level never before seen. That's a good thing! Gutenberg was onto something, and that something has been addictive to the masses.
The back-end of content consumption has exploded as well - with more ways to get access to, find and bookmark, spread, refine, retweet, etc.. As it turns out, many of the consumption tools available today are also contributing to the problem. While as a blog author, twitterer, presenter and startup owner I'm very happy that my messages (from time to time) are spread more distantly that I could've done purely on my own, that feedback loop creates even more noise!
Of course as content is spread around a bit more, that becomes a stronger signal of usefulness versus noise (as both Ron and @writingroads mention) for the search engines and the people running around spreading it around.
Ah, emergence! I *highly* recommend Steven Johnson's book "Emergence: The Connected Lives of Ants, Brains, Cities, and Software" - there is art and science behind feedback loops, and we're only beginning to tap that for increasing findability. (add Linked, Nexus, and Six Degrees as some other great writing on connections, loops, power laws, etc.)
Ah, I could go on forever on this topic, but suffice it to say that unless and until content creators AND consumers put a bit more effort into creating content to BE findable, and creating systems, architectures to ENABLE that findability, well, we're just going to be continue to bury ourselves in content, and that's not going to do any of us much good.
So I'd suggest that as people go about creating new content, they stop and ask, what is this information architected FOR?
Collaboration? Marketing? Community? Innovation? Persuasion? Search Engine Optimization? Or nothing at all?
Identifying the PURPOSE, can help significantly, for all parties involved.
