Not very compelling IMO. They are both basically popularity indexes that move almost cyclically. The arbitrage is almost negligible. When HSX move to real money I suspect the perceived Twit-vantage will disappear.

Not just you. Such is life with graphs in research papers, I guess. Still an interesting read though.

Right, and even for people who are movie goers I would like to doubt. Tweeters are an excellent sample of self-selection. But for opinion polling or commercial market research we need unbaised samples to make predictions.
On the other hand, as tweeting is in its early years of diffusions and thus its users are currently a very special kind of communicators (age, income, location,life style, …) , it would be interesting to try they are representative for something because they are so unrepresentative for the population.

Hmm, looks like we’ve got three data points where both systems were pretty accurate…. and a whole buncha data points where it’s pretty tough to say WHAT’s going on….

Is it just me or is the visualization kinda awful? How about log-log, an identity line, taking out the lines unless they mean something, and showing some metric like R^2 or MSE? … conference paper w/ matlab figures ftl.
