Nope, the opposite, in fact. It still tags, but because it starts with something other than a tag, it's a normal tweet instead of a response tweet. Basically, makes it more visible, so everyone else can see that he's responding, and what he's saying.
What is the purpose of the dot before the @?
Pretty sure it nullifies the tag so the other person doesn’t actually get notified, not sure though never been much of a twit
