In the future from now? I'm sure I'd stay in touch with some great friends I've made on here, I could never leave them as they are very close friends to me, and wouldn't want them to be sad. But, if other friends do decide to leave, it's okay with me, I mean we all eventually grow up over time and I understand that they may want to leave the online world and focus a bit more on their own relationships, jobs, or even kids.
