If I had to guess, I’d say the top innovators were:
1. The advertising industry. They have to create new words by misspelling old words in order to be able to copyright them or to garner attention.
2. The illiterate. They have poor vocabularies, no idea of how to spell the few words they do know, and little knowledge of grammar. They (or their apologists) pass off ignorance as innovation.
3. Comedians and sitcom writers.
When “bling” was being used years ago, it occurred to me that “jewelry” may be a difficult word for some speakers.
