I read this awesome post Ted Murphy about how the world would look like in 2012 with Twitter. My first reaction was to find out if those Twitter accounts actually exist. Well turns out a lot of those do exist. Pretty much every twitter account mentioned there exists except the Parking Meters of SF.
I will give you the list with URL’s here:
1. Winwood != Winwood on Twitter. A gentleman with name Wojtek, from Poland is a TV mecahnic.
2. Whitehouse != Whitehouse of Twitter. 75 followers. No Bio available.
3. Tweetbar != Tweetbar on Twitter. According to their website: Tweetbar is a wicked cool Twitter sidebar for Firefox and Flock. Not compatible with FF 3.0 at the time of this writing but will be, soon.
4. Young != Young on Twitter. Someone of Asian origin. 
5. Lisa487 != Lisa487 on Twitter. How do I know that? Well, actual Lisa487 updated her (only) tweet on Jan 6th. She says “going to work”.
6. Twitair01. No twitair01 account on twitter yet. But there is a twitair.
7. EMT != EMT on Twitter. Someone called Jason Machael owns it. Twit-Squatting???
8. JPMorgan != JPMorgan on Twitter. Apparently, this is a gentleman named Josh Morgan (cool!) who owns the blog http://www.respondingtoopportunity.com/ and finds The_Real_Shaq the funniest person on Twitter.
Personally, I am interested in knowing about Whitehouse, myself.
