Can we please talk about what he says?
Is the topic in any way related to good blog design?
There are quite a few blogs without capitalization and if it is really so important to you feel free to write about it.
IMHO All those comments on design/grammar/font/... in every discussion on HN are mere distractions and add no value.
But speaking of substance, there wasn't really much there. He talked about users like they were an inconvenience and were unreasonable, and that they had some odd psychological issue that needed correcting. Yet he never addressed the genuinely useful features that were removed, or the feeling by users that if they used features in Gnome they might one day lose them, even if the need them.
This is terrible, terrible design philosophy and no one should ever listen to it. The end.
The author's lack of capitalization is not important enough to me to write an article about it and post it to HN, but it was important enough to me to point it out in a comment on the forum page discussing the article.
It seems to me to exemplify exactly what is wrong with the author's approach to features... and by extension, with the GNOME development team's approach to the same.
