A forum/community as refined and mature as this can appreciate this feedback:
Title case is a sin. Please stop it.
I'll use the example used to highlight capitalisation and comma use:
I helped my uncle jack off the horse
I Helped my Uncle Jack off the Horse
Totally ruins the joke.
But more seriously, capitalisation is only for the first word of a sentence, or for proper nouns. Once You Start Capitalising Random Words, you start to destroying meaning.
I ate an Apple in the Apple Store.
Did I eat an iPhone or what?
Side note: I have actually noticed this earlier and I did pedantically go back and de-titled cased my forum post after a certain Power User 'fixed' it.
