I don't really need to show any data for this to be certain

Once upon a time,1 Paul Robertson asked if anyone was using a Pelzmeter to measure green speed. a long discussion followed, and the notifications on my Twitter account blew up.

N & MLSN: what's the connection?

We’ll get to the N below. But wow! I didn’t know silica was such a hot topic! After writing a few days ago (original post here) about silica and green speed, and how it doesn’t make sense to me that silica application could increase green speed, there was quite a response — by e-mail, at this wild discussion on Facebook, and on Twitter.
