Twitter question from a newbie...?

[hopefull411]

I am following just one (really special) person.
This person has quite a lot of followers, say around 345,000. They are following 180 people and I am not one. (that's ok). I am sure this person has the best mobile equipment. I however access Twitter account from my PC.
Questions:
How do these tweets appear in their mobile account? Is there a folder for followers and one for following, or do they all come together in one place?
If I am only a follower can I send a direct tweet? To this point I have only replied.

Thanks for your help!
how would that be compose?

like this?

yes I do @message@person I am following

Your tweets appear in their mobile account also - they are one and the same thing. They come together in the same place because they are just two different ways to see the same thing - the twitter timeline.

You cannot send a direct message unless that person is following you. However, you can send an @message to that person.
