Are we focusing audio signals at aliens and if so, what are we sending?

[Atypical]

Ive heard we are sending twitter messages and the music of Mozart out to specific stars in space?
Response[edit]

In 2012, on the 35th anniversary of the Wow! signal, Arecibo Observatory beamed a response from humanity, containing 10,000 Twitter messages, in the direction from which the signal originated.[13][14] In the response, Arecibo scientists have attempted to increase the chances of intelligent life receiving and decoding the celebrity videos and crowd-sourced Tweets by attaching a repeating sequence header to each message that will let the recipient know that the messages are intentional and from another intelligent life form.[14]

Yes and the conversation goes something like this -

R U Hot?

(75 years later)

WTF?

[DrDave]

NO which negates the second part of your question.

[Starrysky]

We are not sending (except for broadcast communications). We are listening. Nothing yet.
If we would send, like in 1974, see Dr. Frank Drake's message. http://en.wikipedia.org/wiki/Arecibo_message

We send styilised messages showing us as spiffing chaps and chapesses, so if they turn up here, we can surprise them with our greed and want, and glom their technology.
