If I send a tweet mentioning someone I am following then will followers of this person also get notified? Example - If I send this tweet - @Acompany Did you know that @gentleman uses your product. (Where @Acompany is the person I am addressing the tweet to and @gentleman is a person I am following (NOT who is following me)). In this case my query is - Will followers of @gentleman also be notified about the tweet. If the answer to the above is NO then is there any way I can do it. Example - Elton John has over 1 million followers. I follow him, but he does not follow me. Is there any way I can get a tweet out to the million followers of Elton John?
