My brain tends to self-correct what it's reading these kinds of posts, and considering the author of the post has replied to the comments here in the same style, I see two options for the style. It's either done for speed, or the shift key is mapped to something else, making typing one-off capitals harder.
That might equally be a stylistic choice, but I my gut says it's not.
