1. You use the shortest words possible – distilling your vocabulary to sprite-like verbiage (a phrase you would never us on twitter)

2. Compound sentence structure disappears; therefore there are no flowing poetic descriptions.

3. Characters begin talking in short less than 140 character, abbreviated, direct thoughts.

4. When discussing back story, sentences begin with RT @Character’sname and a quote from earlier in the text.

5. You spend time pondering how tweet shrink and url shorteners can be applied to the editing process.

Or, you find yourself writing a short, 5 part post in the affects of Twitter on Writing.
