Replying to [little friend]:
is it for chatting program or e-mailing??
at your first try most people might think if someone who is not in their contact list is a spam attempt, they will also checking your details before they start answering your message. they will look whether you are in the same business with them or not, or if you are bringing opportunity to have business with them. and that is natural. don't use such formal invitation to have a chat. use a light small talk like germex advice.
"hello, is anybody there??" is my magic word to start a conversation with anyone new. they will always reply me when on chat program.
or you can use this for more relax ice-breaking: "knock..knock..!! whassup brother !!"

..just kidding..don't try that one for more serious business.
use an excuse word for some time. "excuse me, do you know how to use this chat program? i am new user here"

..that sounds pretty intriguing also.
the point is just relax. they who didn't answer your message probably in bad mood to talk
