The Tweet to Comment ratio

As of writing, 100 people have tweeted a link to my last blog post, One year on: 10 Ways Twitter Will Change Blog Design and I’ve had two comments on my blog about it.

It made me wonder: how is tweeting changing the nature of blog comments? Is it replacing the blog comment or merely giving a little sound to the normally silent majority who just read a blog post? (Most tweets add little or no commentary on the article.)

Figuring out the answer to this question isn’t an easy task as blog readership numbers and makeup change over time, Twitter has taken off in the last eighteen months or so and re-tweeting tools (especially now that it’s native in Twitter itself) became more standard. There’s so many variables involved that a simple analysis won’t suffice.

Has anyone done in-depth research on the changing nature of interaction with blogs?
