I agree that it may be hard to read all caps and those that use them don't think of it as shouting. Nor those that type/key in all lower case think they are whispering. The internet has brought an explosion of people (a good thing) to the keyboard to share information, many of who never learned to "touch type" but do well with a "hunt & peck" system.
I remember a book from the 1950s (it actually goes back to the 1920s; see Wikipedia article) by Archie & Mehitabel that was all in lower case. Archie, a cockroach, was keying the story/poems and wasn't big enough to hold down the shift key while pressing a letter. What I remember most about the book was, in addition to being in all lower case, how funny it was and maybe I should find a copy and enjoy it again.
Let us all be glad that the information is being presented for others to use. And if the occasion arises with open profiles, maybe do a little editing as it is continually pointed out, WikiTree is a collaborative effort.
