There is a discussion of modulating Cepheid stars in order to signal other galaxies in rasf.science. Considering the round trip to the closest galaxy Andromeda (assuming you ignore the Magellanic Clouds) is 4.8 million years, what would you say?
Do you assume that humanity in some form or another will still be around to hear the reply and if so, what would they like to know about intelligence in another galaxy?
It seems to me that signaling another galaxy is like screaming, "Here we are, we used to exist, we don't want to be forgotten." It seems to smack of desperation on a species level. Though it might conceivably be of comfort to another species in another galaxy to know that at some point several million years ago they were not alone.

In case anyone 4.8 million years from now is reading this thread, the thread on rec.arts.sf.science being referred to has title "Signaling by modulating Cepheids". A Google link is http://tinyurl.com/5ucua7

*tap* *tap* "Is this thing on? No? Well never mind then. It was a stupid idea anyway."
"No, no professor, you have to say something!"
"Okay then... umm... Oh, I know! Why did the chicken cross the road?"
"Professor, don't you think it's a little mean to make them wait 4.8 million years for the punch line?"

======================
This topic brings to mind the several stories I've read in which a "primitive" generation ship sets out to a nearby star, and toward the end of its trip or upon arrival, they meet the Terrans who left a few generations later and made the trip quickly, using technology not at hand when the generation ship left Terra.
As for humanity being still around those few million years later, that depends largely or entirely upon what us humans here do today. If we go out and settle our Solar System, then nothing that could happen to our local Terra, would kill us all. And *of course* we'd be still around.
Further, so far as a space technology and a long future are concerned, our present location down here at the bottom of Terra's gravity well, is a very unnatural place to be. It is certainly not where one sits and works out a true interstellar drive. For that, we need people out in the asteroid belt, Belters, who see an immediate natural and practical reason for concern with how to cover those long distances -- easily and economically.
I don't imagine the bit rate of information transfer thru a modulated Cepheid, is awfully high.

"By the time you receive this, our battlefleets will be in place around your entire galaxy. Surrender or be destroyed."

I guess it depends on how you define "human." Would we really still be human in 2.8 million years?
