I think you see this for the same reason you see people endlessly debating/discussing version control systems, GTD, IDEs, OSes, keyboards, mice, browsers, etc. etc. etc. They're all just tools, and yet we (myself included) spend far too much time talking about them, and not nearly enough time using them. True, some of the discussion is merited and is rooted in useful thought about real differences between tools, but much of it is over analyzing.

I think much of this could actually be rooted in fear, which drives procrastination in lots of people - more than most of us realize, I think. Merlin Mann's gave a great talk on fear: http://www.youtube.com/watch?v=Lk0hSeQ5s_k

The key is to understand that fear isn't going to go away completely, and to still keep doing, even though you're scared.

Enough talk. I'm going to go build something now.
