48.) Listening too long to someone you agree with is the most dangerous thing in the world.

Seek out new ideas and fresh perspectives.  If what you believe is true, not only will opposition not sway you, it will hone your reasoning and strengthen your argument.  See confirmation bias.

The toaster I use for two minutes each weekend has a removable crumb tray for convenient cleaning.  Meanwhile, the keyboard I sit at for ten hours each day requires a five dollar can of compressed air to clean, and the word “clean” is being used here very loosely.  A team of engineers needs to get on this A.S.A.P.

47.) The quality of a person’s argument will often tell you far more about their trustworthiness than the actual facts of their argument.

I ask Google all the questions I’m too embarrassed to ask other people. Google has officially played more of a role in my sex education than my school teachers, my parents, and my first three girlfriends combined.  I find that extremely frightening, because it’s not what you’d call “the normals” who write in-depth articles on exotically named sex positions.

It makes me extremely nervous when an application asks me as I exit if I want to save any changes to a document that I could swear I didn’t alter.  Some programmer needs to get on this issue.

I don’t know what people did before GPS navigation systems.  I honestly don’t.  I just wish that whoever wrote the software behind those systems would develop an “Avoid this Neighborhood” routing feature that would automatically guide me around the neighborhoods that make re- re- lock my doors.

If Thomas Jefferson were alive today, I’m pretty sure he’d be a pissed-off blogger.

31.) Be wary of consistency.  It’s the surest sign of a lie.  Even if it’s a lie you’re telling yourself.

It’s time to stop releasing new video formats.  The industry thinks that it’s tricking us into re-purchasing our collections, but all it’s actually doing is burning out video collectors, destroying our last reason to buy rather than rent, and frustrating us.  I had hundreds of VHS tapes, many of which I bought in high school, before cable was available in our town.  In college, I bought dozens of DVDs.  Today, I have three Blu Rays, all of which I received as gifts.  I will not be purchasing videos in the next format.
