I’ve seen a few posts from the Pew survey talking about the decline of blogging and the rise of Twitter. Boyd has the best link here but my first thought was:
Isn’t Twitter a form of blogging? RSS feed? Reverse chronological order? Comments? Blog roll (of sorts)?
Last I saw there were 200m blogs being tracked by Technorati – of which 10m or so are probably legitimate (not spam) and active. There are 160m Twitter microblogs and about 6m tumblr accounts – also blogs.
So like RSS, where the act of subscribing to a feed may be on the decline but the use of RSS is still alive and kicking as the backbone of the Internet, blogging as an expression of longform content may be waning – but blogs as a technology and trend is very much alive and kicking.
