[plt-scheme] Reading all of the SRFIs?

Any time I start learning something new I figure that I will read
everything, at least once, at least skimming it, for example.

I figured that I ought to read the SRFis in the same manner, but have
been sort of avoiding them.

Two things happened that seem to warrant reading all of them:

1. I learned about the list filter method.

2. I learned about the list-ec method.

These are interesting things, and in the eyes of newbies they are hidden away!

What is your folks take on reading all of the SRFIs?
