No your not alone i don't have them either and frankly I'm sick of people asking me if I do.. I don't and never will...
I only have Skype for wrk, & I don't have kik either.
I have Skype because I've lived overseas previously and still travel quite a lot. Being able to have free calls back home from overseas is fantastic and being able to video chat with my daughter (who is 5) whilst I'm away make being away much easier. I don't even know what K1k is.
