Is B2B Content "Likeable"?

With all the discussion about Facebook's new "Like" (or "Recommend") button for the web, I thought it would be worthwhile running a small experiment to answer the following question:

Do the readers of B2B content share more on Twitter or Facebook?

I will admit that I have certain biases, and I don't think that the human brain is very well adapted to truly merging business and social relationships as I wrote previously. However, in the interest of science, I thought the experiment was worthwhile.

I have reduced the automatic "sharing" options on each post to two - one that shares on Facebook, and one that shares on Twitter. I have historically been sharing content only on Twitter, so it has a bit of an advantage, so in order to somewhat compensate for that, I have added the Facebook sharing bar to the top of the post.

I could be proven wrong, but I suspect that, when I tally the counts a month or so from now, we'll see very little activity on Facebook in comparison to Twitter.

What have you seen for B2B content? Does it become shareable on Facebook?
