I would have thought that Glossophobia was really fear of tongues (possible a fear of french kissing?). However, Roget also list fear of speech as logophobia, lalophobia and phonophobia. I would consider that logophobia carried the sense of fear of public speaking and lalophobia the much more rational fear of having to listen to public speaking.
Graphophobia, scibblephobia and scribophobia are all given as the fear of writing. Typophobia is listed as the fear of writing for publication. I'd go with modern usage and suggest egraphophobia for fear of writing email and itypophobia for fear of writing on the internet. However, I can't find a word for the fear of reading so I'm open for suggestions on what a fear of reading/recieving [email might be although spamophobia is clearly a part of this fear.
