Topsy Twitter Stats...they are pretty much the most trusted, most used Twitter analytical company on the internet. Sentiment score is overall positive/negative mentions (100 - most positive, 0 - most negative), and they have an algorithm that also adjusts for time of year/holiday/etc to accommodate for the overall mood of the time period.
Taylor Swift: 321,518 tweets over the past week.
Sentiment Score: 90
Katy Perry: 202,564 tweets over the past week.
Sentiment Score: 71
But I thought the general public was on Katy's side?
Let them believe what they want, we know the truth.
