You know, I think this is worth talking about. Wikipedia’s guidelines are there primarily so that facts can be verified; so that things can’t be made up. The same guideline that makes it hard for FLOSS articles to survive makes sure that people aren’t allowed to post articles about, say, their cat and its idiosyncrasies.
The goal would be: how can we make this not fail? What *would* be reasonable requirements for FLOSS articles? I’m sure that if you worked with, say, the WikiProject Free Software, you’d be able to get a special notability guideline for this subject area.
The key is determining, well, what does make something worth writing about in the FLOSS world? Case-by-case deliberation is fair enough, but if the underlying guidelines don’t help the subject area, it’s not going to work out well in the long run.
