That's a thing! I see that a lot. I like it when I see it, but I don't do it myself - as you say, too time consuming. I am picky about title case, though. I don't like to see conjunctions capitalised. The Time of Angels, Grace for Drowning, Journey to the Centre of the Earth. Journey To The Centre Of The Earth looks terrible, to me. Wildly inconsistent with abbreviations, though. JttCotE, JTTCOTE - depends on my mood.
Also, looking back, at the time I mentioned dashes, I'd used at least one, sometimes more, in each of the last seven posts. It's a disease, a brilliant disease.
