Which would you choose? Weibo, Wechat, Facebook, Twitter, Linkedin, Youtube commenting, Tumbler, a certain forum we all know, some other forum, I hear Renren's old hat these days, what else are people on?
If I really had to choose just one digital social connection, I'd keep a Wordpress blog. I mean, anything I post anywhere turns into a blog-type post anyway. But I don't know what the other sites and services are like because I don't use them. This question about social media is prompted by having pretty much no social media presence anyway (and yet still getting pinged by Linkedin today). I have a Twitter account that I literally never use. I have a Photobucket account that I sometimes use. I was on Linkedin for about a week. I have email of course but that's not "social".
What would you stick to if you had to stay with only one?
