The reason I asked you if you were following me is because if you were, then my article would have been presented to you.

The other reason that the algorithm presents someone is because you've read something similar. So, for instance, people who read Caren White, Jessica Wildfire, and Umair Haque will often follow me because my name is suggested to them. Often when I read through who people are following, I see they follow the same people. That's because the algorithm presents them with articles that are similar to the one's they read.
