Greetings! Say Hello To Your Substitute Teacher

Good morning, class. I am SIGNAL TO NOISE, and I’ll be guiding you through this glorious Saturday, and thanks to Brooks for giving me the keys for the time being.

Jack Black, substitute teacher

Call me S2N. Like everyone else, I am dependent upon the grace of the readership (namely, you), so send any and all tips to, or if you prefer AOL IM, s2nblog . So, let’s enjoy this lazy Saturday, shall we? I’ll be along in comments during the day, too.
