I also follow the "'stuff' my dad says" guy, as well as Rainn Wilson (from The Office), Michael Ian Black (SO inappropriate but so funny!), Chris Shiflett of the Foo Fighters (as well as the Foos themselves), a few other bands, Wil Wheaton, CNN Breaking News, The Onion, a couple of local sports journalists, a hockey news/rumors blogger, WDW Today, and some merchants I've bought from online before. I've found out about a lot of online-only sales, promo codes, etc., that way.
