We've just read Jay Adelson's piece regarding the democratisation of information, care of the internet's burgeoning blogging community.  He describes the situation well - the way we assimilate knowledge is changing due to the proliferation of 'news' outlets (we're all increasing coming across information regarding new technologies from independent blogs and not from conventional news sites). 

Despite this explosion of information I think the power still lies with Google.  You can only access a fraction of what is out there without a search engine and the rules that govern SEO are constantly being rewritten.  Which really means that those complying with Google's latest guidelines get the largest amount of traffic.
