One weird thing that I've discovered is that there seem to be no correlation between who I consider a great hacker and how many followers they have in top 10k.
For instance maxogden [1] and mafintosh [2] are both in top 1k but have only 6 top 10k followers each. Where as I [3] are not even in top 10k and have 9 followers in top 10k.
