Once upon a time and it wasn't really that long ago, you would post a blog entry and people would either comment on it directly, or they'd write their own post and link to you.
In 2011 with people cross-posting their RSS to multiple targets such as Twitter, Facebook and LinkedIn (and a load of other places) some people are saying that they aren't getting the volume of comments they used to. At least not on their blogs. They're seeing the reactions on the other platforms / networks
I've seen this to a certain degree, but what about other people? Is this common? A trend? A fad?
