Accidental
When I was figuring out the headline roundup entry template at Pagan Vigil, I started with a div that specified 125% font size. When I popped in the h2 code in between the div markers, it made the h2 heading bigger too.
Meanwhile on the clipping template, the h2 comes before the quote box, Which means the h2 heading in those entires was smaller than on the roundup entires.
I was going to fix it, but I decided it looked better that way.
It wasn't something I planned, it just came out that way and I liked the way it worked. That's happened a few times in the past.
