I been revising the Drake Equation, and was very surpriced to get the value of N at only 0.3. But I guess that means I've solved the Fermi Paradox :D http://en.wikipedia.org/wiki/Drake_equation

However, I recall one can do the Drake Equation (or simular) looking at the total number of stars in the galaxy / universe and not only the creation rate of new stars. I expect to get another result using that method, though I know the R*-value in the Drake Equation in the link above is partly based on the number of stars in the Milkyway.

The reason for doing the Drake Equation (other than looking at how I've changed each value over the years), is that I've found the first radio broadcast to take place on christmas night in 1906. http://en.wikipedia.org/wiki/History_of_broadcasting . That means the electromagnetic waves reach out at 107 ly. That covers some 2,330 stars (calculated from the 1.000 nearest stars found within 45.92 ly according to this webpage: http://www.dudeman.net/spacedog/starmap/1000.html ). Putting that into the equation I wanted to find out what the chances were (according to my estimates) that anyone could have received our signal so far (107 ly away), and how many could have sent back a signal after receiving a signal from us, which we potentially could have received already (53,5 ly away).

I expect you Drake Equation fans out there have discussed values of the equation for ages, so not trying to start yet another discussion here about that, but in short, what are your values? And what if you put those values in the fact that some 2.330 stars could have received our signal thus far?
