One of the things that has made blogs such a vibrant medium is how comments can provide as much insight and information as the blog post itself. The ability to have a conversation with the blog writer, as well as other people leaving comments is part of the “goodness” of blogging.
That said, it is interested to see how Twitter is becoming a place where people comment on blog posts, along with providing a link to the blog. It raises the issue about whether Twitter could kill blog comments or, at least, seriously wound them.
Twitter could be becoming an increasingly popular place to have comments for a few reasons.
One, it is more of a popular medium than leaving a comment on a blog. On Twitter, it’s easy for people see what you think about a blog post, rather than having to visit a blog or search for comments. At the same time, Twitter also lets people show and share other people what they have been reading.
The rise of Twitter as a way to comment on blog posts is just another way comments have become more scattered. These days, you can leave a comment about a post on places such as Friendfeed, Facebook and Hacker News.
In many respects, comments have escaped, and there’s no way to put them back in the Genie’s bottle. Of course, it does create an opportunity for a comment aggregater to take advantage of this conversation fragmentation.
