Young people (like me) use lowercaps like that all the time. Around 50% of the young people I know purposefully turn off auto-caps on their phone.

Why? I really couldn't say. I think we just like the feel of it. The only reason I type with proper capitalization on HN and my blog is because I know older people read it.

I’m middle-aged. I’ve noticed in the last few months more and more articles with this style. Something I’ve never seen before in blogging or article writing.

I usually notice the style at some point but this time I had no idea until this other commenter pointed it out. I guess I am getting acclimatized.
