"Open Source is Really About Documentation" and many other things...

Interesting post "Open Source Is Really About Documentation – Twisted vs. Tornado", which is summarized by the author as:

if the documentation for an open source project sucks, nobody but the most hardcore developers will use it.

I'll give a different summary: Developing good software is less about developing and more about many other things: documentation, maintaining stability, good release practices, good patches, etc.
