Readability is a complex matter in that it depends a lot on the reader, their expectations, and how well they handle some cases vs others. On title case in particular, I wonder how you would feel if it was applied to everything in the text, and not just the title. Would it be more readable ? For me personally it absolutely wouldn't and I'd be infuriated after three lines. Then if most people were on the opposite side, I'd think we'd have at least a few prominent use cases where all the text would be in title case, and I can't think of any. Is title case's point to just make it clear it's a title ? If so, we have so many better ways to convey that (bold, underlining, spacing, positionning, bullets and markers etc.). On the baby and the bath water saying, the more I think of it the more I see Title case as just a relic of some old practice I'm not sure why we cling to in this day and age...what's the baby, what am I missing ?
