The good news is that changing your name on Twitter is as easy as going in and editing the name you originally chose. For instance, I went from being “astrout” to “aaronstrout.” However, I wanted to keep a 2nd account with @astrout since I’ve got some equity in that name (and it’s posted in about 250 comments across many blogs).
So here goes:
1) Open up a second Twitter account with the new name you’re going to use (for instance, I did this with “aaronstrout”). NOTE: you’ll need to use a second e-mail since on Twitter you can only have one account per e-mail address.
2) Now change this address by adding a “1” or any digit after. For example, I changed mine from “aaronstrout” to “aaronstrout1”
3) Go back to your original twitter account and change your old name to the new name. For example, I changed from “astrout” to “aaronstrout.”
4) Now go back to your new account and change that to your old name. For example, I changed it from “aaronstrout1” to “astrout.”
