No, I don’t think so, although if you were to just skim the top of this article, you might think so, Blogs Wane as the Young Drift to Sites Like Twitter – NYTimes.com. Instead, read the entire article: it’s a great overview of what is happening in social media in 2011.
I would like to add that regardless of the platform, what is happening is that it getting easier to share information with others, and people are capitalizing on this. Furthermore, more and more people are using these tools. Alot of what people are doing now could be done with minicomputers in the 80s and PCs and BBSs in the 90s.

I expect by 2020, there will be even more platforms and a wider and richer way to share information. It’s exciting. Whethere blogs wax or wane is besides the point in the longer term.
