Specification of follower relationship

[mjuarezm]

Thanks for sharing source code and data.

I'm trying to understand the direction of the follower relationship in the data. Is it correct that Node2 (second column) follows Node1 (first column)?

A related question: when I list the probabilities grouping by User2, I obtain zero variance (all the probabilities for a given Node2 user are the same). Why is that?

For example:

Node1	Node2	P
hippygirl37	003a04f8c2054b7	0.001695
totemranch613	003a04f8c2054b7	0.001695
joydcarter	003a04f8c2054b7	0.001695
irshroz	003a04f8c2054b7	0.001695
tovaod	003a04f8c2054b7	0.001695
...	...	...

Thank you!
