I mean, I added lila, and she & I totally don't agree on the oth spot! But she loves veronica mars, and so do i! :)

I don't fan people who have nothing in common with me, and haven't contributed much.

Everyone likes different things. It's nice if you have the same interests though and there has to be at least one thing that you agree on.

Sometimes I just don't have anything in common with them and they haven't 'done' anything, just like skeloth said

but sometimes its nice to not have anything in common with them to see their different views on things...plus, if they added you in the first place they must think they have something in common with you or even just like the content and comments you have made! ♥

nope

obviously if you have no spots at all in common then it seems a bit strange but you don't have to agree on anything really so long as you enjoy one anothers content

i sometimes will wait to fan someone simple cause I have never seen them and I want to feel them out but never because we don't like the same spots.

No not that I am aware :S

No, I generally fan people because I see good content they've added.
