Yeah I had two pretty good efriends I met on /r9k/ decades ago back in Skype/MSN threads.
We silently drifted apart (probably partly because of my obsession with a stupid MMO and partly because they had better things to do as well) and one day I just uninstalled skype without getting an alternate way to contact them.
I feel guilty for not being a better efriend after so many years. but I also kind of don't need people in my life.
