A couple weeks back I raised an eyebrow about Henry Blodget’s suggestion on his website, Business Insider, that Facebook’s Sheryl Sandberg should be the next Treasury secretary. Given her lack of relevant experience, it seemed an absurd suggestion.

Now I know why Blodget really made it: Sandberg is the lead speaker at a Business Insider conference. Tickets are a mere $1300 a pop.

So Blodget was either thanking her for agreeing to attend his conference, trying to persuade her to attend his conference, or trying to boost sales for the conference by putting the rumor out there she might be the next Treasury secretary.

If something doesn’t make sense on the face of it, there’s usually a reason…
