Well, there's a beta thing on Twitter, Verified Account.
For example,
http://twitter.com/DAVID_LYNCH"With this feature, you can easily see which accounts we know are 'real' and authentic. That means we've been in contact with the person or entity the account is representing and verified that it is approved. (This does not mean we have verified who, exactly, is writing the tweets.)"
So, even if there was a verified Winona-account, it could still be just a publicist.
Some people take Twitter too seriously, meaning, they actually post really mundane things they do. I've posted two tweets, thus far, a test at opening, and about a local fire.
