Apropos my recent post outlining why open source is not very popular.
I've spent some time researching useability, both in computer software and other areas.
The post was necessarily brief - it only outlined 5 general trends and was light on context, explanation, and supporting examples.
A better treatment would explain all the trends that I see (perhaps a dozen) with more explicit explanations for each. Unfortunately that's not appropriate for a blog post [Slashdot] comment.
