nah you only have to be following each other to send private messages
no if its a big tweet and your fans are letting u know then u can see the tweet from whoever easily then u can respond to that person,u dont have to be following them on twitter to respond,but maybe one of them follows each other,maybe both
I am talking PRIVATE messages... you have to be a follower.
Just to see a msg, you don't have to be a follower. For instance, my name is @stoggio. Anyone who puts that in their open msg, whether sent to me or... I can go to '@mentions' and see EVERYONE who put @stoggio in their messages.
Direct msgs are different though. The only people that can send me direct msgs are people who I follow.
but if you look at Ja's reply, he put 50's twitter name in it. Therefore, when 50 goes into his '@mentions', he can see that Ja sent a msg with his twitter name in it.
