I personally dislike all lowercase, to me it feels like not greeting someone but I don't get GP's argument either.

The article is a bullet point, yes, but some items have multiple sentences with no caps

funny you should say that, i frequently feel uncomfortable greeting people, because i don't know what greeting is appropriate. (this is exacerbated by the fact that i travel a lot and different cultures have very different ways to greet each other)

so if you feel that my lowercase writing is like i am not greeting you then that's the feeling i probably induce in others frequently. welcome to my world :-)

(multiple sentences appear only twice, btw, it's proof that the writer intended to write all lower case, but not strongly noticeable (to me at least))
