The idea of a surging trend vs a slowly building trend should inform on how twitter does its own 'trending topics' selection right now, and could be the basis of another service that analyses trends. I can imagine twitter is only looking at the surge in topics at this moment, vs the long tail trend which has a lot of chatter over a longer period of time. Another measure would be to look at the entropy of tweets. A measure of the amount of original tweets vs re-tweets. Iran probably has higher entropy than MJ - an indicator of a higher level of conversation.
