Check out this WebProNews interview with Rand Fishkin of SEOmoz.  It is good throughout, but it has a particularly interesting section up front involving Twitter and linking.

“A couple of years ago, when someone would see an interesting piece of content, they would link to it. Today, when this happens, people tweet it. So, what does this mean for link bait?

Fishkin response, “…essentially, Twitter is cannibalizing the Web’s link graph, and it’s doing so in a disproportionate manner for more social media forward industries.”

As an interesting side note, I saw this video a couple of days ago (finding it on Twitter).  I should have blogged it then, because it was hard to find today!

I think it’s time to start blogging more than tweeting.
