Where in Google's blog post do they claim to still follow the link? They provide no technical details for their process, so if we're speculating, it would make far more sense that rel=nofollow adheres to the same guidelines as a meta/robots.txt nofollow.

And this speculation for the "shared on" functionality doesn't exactly add up, either. If they're not following links with rel=nofollow, why should Google be legally or even morally responsible for storing a massive and entirely extraneous relational database, and then checking against it every time they follow a short URL from another site, just to see if it was shared on Twitter at some point?
