In the early days of blogging, there were no lack of comments because pre-Twitter and pre-Facebook, it was one of the few ways that people could engage with content.
Today, there are lots of options – Twitter, Facebook, LinkedIn, Friendfeed, etc. While comments are still alive, my take is people aren’t as enthusiastic about them, and they don’t have the same cache as they might have a few years ago.
One of the biggest impacts on the comment is Twitter, which lets people post a mini-comment about a blog post or retweet a post they find interesting. A Twitter update or retweet is a faster and more efficient way to respond, and whatever the person has to say gets instantly distributed to their network.
So the question that begs to be asked whether the update and retweet has supplanted the comment as the way to engage with blogs? While comments are still happening and much appreciated by bloggers, Twitter is becoming, in many respects, a blog comment system in and of itself.
