4e Monster Balance

The great 4e D&D blog Square Fireballs hadn't been updated in, like, forever, but I checked it today and found one new post (dated June 12, so technically it's not new) on the issue of balancing the various categories of monsters (minion, standard, elite, and solo). If you're at all interested in the underlying logic of 4e encounter design, I highly recommend giving this post a few minutes of your time.
