A number of months ago, Ed Finkler started a discussion in the PHP community about "MicroPHP"; to summarize, the movement is about:

• Building small, single-purpose libraries.
• Using small things that work together to solve larger problems.

I think there are some really good ideas that have come out of this, and also a number of questionable practices¹.

One piece in particular I've focussed on is the concept of so-called “microframeworks”.
