Yes, WordPress automatically corrects all instances of the spelling with only one capital to the CamelCase version.
Nobody cares about CamelCase!
There really is no need, especially in this day and age where lowercasewebaddress.es and #hashtags are common and easily read. Except, of course, if there is ambiguity. It’s not 1994 anymore. The internet is no longer something new and exotic. wedontcare is as easy to understand as WeDontCare.
How anally retentive can one site get? Does Nintendo go around autocorrecting all comments on Miiverse referring to “Pokemon”? Does TMZ do the same for “Beyonce”? People can spell a word CamelCase, with one capital, with or without an accent. It really doesn’t matter.
Please stop it.
