Like the expression, "I'm all ears" juiced up for the Internet.
To be used in e-mails and mostly text or instant messaging and chat.
I am ready, willing and able to read what it is you are typing.
All my attention is on what you are typing.
(Like an IM conversation or chat room conversation)
Conjunction_Vitus: Hey, are you paying attention to what I'm saying?
Jut_Unions_Convict: Yes, I'm all eyes.
