Stupid question but...do kisses mean anything at the end of texts?

Anonymous
I got a text off this girl who I'm 75% certain is interested in me. At the end she left two x's.

Not to over analyze but I noticed that on Facebook, she always replies to messages with one x unless it's a close friend.

What do people make of this?
