lynn's internet english idiolect

lynn's internet english idiolect

I wanted to write this little document explaining how "the English I use on the Internet" differs from the English you might read in a newspaper.

I should note: these rules apply in a "direct messaging" or "chatroom" kind of scenario, and also on Twitter. Elsewhere, especially in long-form forum-style environments where I have paragraphs and Markdown, I tend to tone it down. I'll still use emoticons and abbreviations, but try to capitalize and punctuate in a standard way. (This seems kind of common when I compare, say, StackExchange posts versus chatrooms: plenty of members capitalize in the former but not the latter.)

capitalization and punctuation

  • Sentences don't start with a capital letter.
  • I almost always capitalize the word I, because I think it looks weird otherwise. I sometimes lowercase it for effect, as sort of a "hushed voice" thing.
