4. twitter: friends, followers, and setwise operations
restful and oauth-cladded apis
no, you can't have my password
a lean, mean data-collecting machine
a very brief refactor interlude

summary
5. twitter: the tweet, the whole tweet, and nothing but the tweet
pen: sword∷ tweet: machine gun (?!?)
analyzing tweets (one entity at a time)
tapping (tim's) tweets
who does tim retweet most often?
what's tim's influence?
how many of tim's tweets contain hashtags?
juxtaposing latent social networks (or #justinbieber versus #teaparty)
what entities co-occur most often with #justinbieber and #teaparty
tweets?
on average, do #justinbieber or #teaparty tweets have more
hashtags?
which gets retweeted more often: #justinbieber or #teaparty?
how much overlap exists between the entities of #teaparty and
#justinbieber tweets?
visualizing tons of tweets
visualizing tweets with tricked-out tag clouds
visualizing community structures in twitter search results
