Tweets were pulled using the search API, and I dumped the text to a file. Then I filtered out all the hashtags and usernames (along with all instances of “RT”), because otherwise they obfuscate the interesting stuff.
This is a reasonably simple representation of the word cloud, if anyone would like to funky it up a bit, the corpus of text can be downloaded.
My impressions of it? There’s a lot of positive words in there, and many of the obvious memes of the conference are represented (although, surprisingly, I don’t see any representation for kittens). Also, as always with these things, it can get a little meta, with ‘Twitter’, ‘Tweet’, ‘hashtag’ and so on all featuring prominently (though another surprise is no ‘wifi’, which almost always makes an appearance in conference word clouds).
I will post more complete impressions from the conference when I have the time to write it up.
