It has to be another technological civilization "similar" to ours,
capable of interstellar communication. The degree or level of
technology and intelligence required is not well defined. Too far
below our current level (say 100 years even!!) and forget it as there
is no technology capable of interstellar communication. Too far above
our level and we probably couldn't understand or be able to detect
their technology and forms of communication. For example, a very
highly advanced technological civilization could use "worm holes" in
space to travel and communicate and we'd never know a thing about it
(see no evidence of it)

Let's say that there is this advanced society with those interstellar 
communications skills.

Are they likely to broadcast in a manner that we could locate them or are 
they more likely to only listen to the more primative modes of 
communications that we are are using.  

In other words, would they try to let us know that they exist or would 
they simply keep track of us?
