I think when it come to great content we should all look to the original experts at content creation - journalists. Ask yourself - is this blog post newsworthy, is it relevant, is it unbiased? Put yourself in the readers shoes and be honest with yourself - is this content really worth the readers time? I mean web content producers have it the hardest - pre-internet journalists weren't competing for nearly as much attention as now. For print media, readers may be stuck with only one magazine in the bathroom or plane - so that is what they will read. The web is inherantly a browsing platform - so we are always looking for something better. That is why online dating can be so discouraging - or so my friends say ! ; )
So be very critical of your content. And obviously put the time into what I call "syndicating" the content out to social media, bookmarking, etc.
