Favoriting tweets

A little ramble on favorite-ing tweets:

When I want to read something later, when something's funny and/or when I want to remember something, I give it a star. (still looking for a better system for this, a place to save them all or something like that because Twitter sometimes kills the old ones?)

As of late, Twitter has added a function that emails you when someone gives one of your tweets a star. And that has somewhat made me a little conscious about staring things. Do I want that person to I know that I liked what they just wrote? On the one hand, why not right? It feels a bit like a confession between me and the tweet's writer. But it's also a little bit of a secret.
