Do you have "a facebook?" A facebook page? A facebook account? A facebook profile?
People don't "friend my facebook" they "friend me on facebook," so is it "a me on facebook?"
Twitter? Twitter page? Twitter account? Twitter profile? "Check out my twitter," but do people say "I have a twitter?"
GitHub? Do people say "I have a github?" Check out my github? Check out my github account? Follow me on github? Follow my github account?
Didn't all this start with myspace? Is it a my myspace or a myspace? Do you have a myspace or a myspace page or a my myspace page?
Is every sentence in this post a question? Isn't it exhausting?
