So I found a very fun site that George Ford will now yell at me for him wasting countless hours playing there. Tagxedo not only lets you create word clouds but also allows you to create custom shaped word clouds. I created a list of my top commenters over this year. By duplicating the names of the most frequent commenters in my list, it allows you to see them bigger than the rest. And the custom shape? You might recognize it as the silhouette of my famous green hair gravatar.
What is nice is that Tagxedo will take your blog or twitter feed and automatically create a word cloud for you.
Right now adding custom shapes, like my gravatar, is free while it is in Beta but head over and check out this video on 101 Ways you can use Tagxedo.
