Well...alien is an attractive topic but so far there seems to be no concrete progress. Many people claimed that they have met alien but so far there is no strong evidence. The story-telling is good but not rigorous from sciencitific point of view.

Re: Not a good idea
Optics make more sense than radio waves. Light travels faster than sound, and if you want to cast a wide net in the search for artificial intelligence, the smart thing to do would be to use light. 

Although, I think realistically if intelligent life forms outside of earth wanted to talk with us, they already would have.

Re: Bad idea
When we say "speed of light" we mean speed of light in a vacuum. Space is close to a vacuum, but not quite. Because of that, the bits will, far enough out , be traveling at ever so slightly different rates of speed, so they will tend to interfere with each other, and the messages will be, at best, blurred.

The late Carl Sagan wrote a wonderful book titled "Intelligent Life in the Universe". In it, he described how, if a civilization exactly like ours existed on Mars, we wouldn't be aware of each other until WWII or slightly thereafter. That's because at that point, we put out enough radar and TV signal to alter the the profile of the planets radiation pattern far enough away from what it would naturally be to alert an off-planet observer to the fact that the earth is occupied by technological beings.

So, that would mean that the observers would be anywhere from 70 years behind us to an infinity ahead of us. I agree with the pessimists that we definitely should not be pulling the lion's tail.

Bad idea
This has been discussed ad inifinitum online and elsewhere, but I do believe that Aliens visiting us would indeed be like Columbus and the indians, only this time we wouldn't be Columbus.

I am writing this on the June 23 2367 though I doubt whether anyone will ever read it.

The aliens arrived a few months ago and began systematically destroying out cities and the few space colonies we have on the moon and Mars.  They are also systematically capturing us humans for what purposes we cannot deduce, but millions of humans have been taken alive by the aliens.   Those of us who resisted were killed by some, we believe, invisible force field.

Few attempts at communication with the aliens have been successful, but it does appear that they were able to lock on to communication beams sent out early in the 21st century.

Apparently some darn fool thought it was a good idea to broadcast to the universe our location and level of civilization.  And these aliens picked up the signal and using their advanced technologies were able to successfully track us down.

The end of civilization because some scientist wanted grant money and so invented a project to tell the universe where we live.

Not a good idea
This concept assumes that all ETs will be benevalent beings. I think that the evidence points to ETs being more like us than not (agressive decendants from the near top of the food chain) so this really just makes our planet more vulnerable in the great scheme of things. 

We should stop this idea before it gets out of hand and draws the attention of someone we don't want to meet at the wrong point in our evolutionary path.
