Nope, looks alive to me. Lots of new blogs even within the past week or so. The veterans may post with lesser frequency, so clicking around the bottom half of the blogroll will usually net you a visit to a Golden Age codger with Classic Content. Still feels very vibrant. Lots of things happening all the time, self-organizing things, viral things. This is life itself, and the people who know how to live it.
Joe’s been building up a magnificent selection of videos the past couple years, in addition to the meticulous posts on his blog. A good Facebook (and why not G+ as well? Google cares, and that’s useful for SEO) campaign would be easy with that depth of content to draw from.
