Over the years I've come to the belief that there are two kinds of programmer in the world, no matter what technology they work with, lets call them:

1. Day Programmers
2. Night Programmers

Now - day programmers are the most prevalent in this industry, and you find them mostly in organisations which have historically tolerated a certain amount of inefficiency. Day programmers have the following characteristics:

1. They are mostly led and seldom lead.
2. The have trouble coping with complexity.
3. They cannot visualise a solution.
4. They don't load their development tools at home.
5. Typically don't participate in the development community.
6. See programming as "just a job".

If you are a night programmer, you probably have trouble understanding why a day programmer even entered the industry, and the reason is because they are motivated by different things than you are. The characteristics of a night programmer are:

1. They mostly lead (or drag kicking and screaming).
2. They develop deep understandings of complex things.
3. They can visualise a solution and have a sixth sense around design.
4. They load the alpha/ctp/beta version of tools at home.
5. They participate in user groups and mailing lists.
6. See programming is as vital to them as breathing air.

If you are a day programmer, you look at the night programmer and think that they don't have a life. And you laugh at them when they come in excited about some cool new trick they can do in the framework.
