The human readable version:

You will not hold me or any contributors responsible for anything that happens while you are using this program. No matter what.

If you send a direct message to your violently jealous girlfriend explaining where you were last night, she never gets it, and savagely kicks you between the legs the next time she sees you, I won't foot the hospital bill (though I would understand if you needed a drink - call me up).

If you upload pictures to Twitpic of that wild party last weekend - the one where you made out with 3 strangers and the pizza delivery guy, and they instead end up in your grandparents's "our angelic granddaughter" Facebook album, I won't come with you to explain or apologize (unless your grandma bakes nice pies - mmm, pie).

If the program somehow causes the end of the world in 2012… well, then you won't be around to blame me anyway, will you?
