Sort:  

any upvote you give her (comment or post) will increase your "friend-ranking" (which depletes over time but never goes to zero as you receive cuddles back from her, a single upvote and you'll technically be considered for cuddles-back eternally, the frequency will decrease though, albeit that's heavily randomized).

Following her does nothing atm. But that might be a criteria for other random visits by her at a later stage.

I gotta stop giving out all that insider information :P lol

What insider information ;) (shhhhhh)
