I used to use YIM with a few selected friends but dropped that long ago. I'm not very good with IM's, as they are a bit too... instant for me. I'm weird like that. Why I prefer notes, they go at a pace I can keep up with without stressing.
'No, because none of them will add me...' and 'I don't use anything like that.' both are accurate for me. I don't use Skype but if I did, who would want to add me? Plus, I can't really speak English (I know it but I'm useless when making a use of it... I mean real taking).
most people I know well enough to talk to I talk to outside of skype. one fairly well known artist here I talked to on skype originally, but then we became FB friends and I talk to her there. another artist I know I met through tumblr I talk to on skype, but she's like the only person I regularly talk to on skype because she doesn't really have any other platform for me to talk to her through.
