Of 4,467 tweets, these are my most frequently used words over the past year. Posterous should be amazed that it made it, while Alltop and Changemakers didn't at all! :-)
UPDATE
Right after I used Tweet Cloud, I started seeing tweets telling me to "beware" of the application and to revoke its access to my account. Strangely, I can't find any information on any malicious activity--just lots of folks saying to beware. I'm wondering if the warnings relate to the automatic tweet the application creates after the cloud is produced. For me, I just unchecked a box during the cloud creation process, asking them not to publish anything from my account, so I had no problems. I still revoked access just in case there is something more serious afoot. But I sure hope this warning isn't empty and we aren't driving business away from a cool application!
Does anyone have more info on this?
