Hell. We have been doing that for 120 years already. Every thing form ship-to-shore Morris Code from the Titanic, to Amos & Andy to I Love Lucy, to Obama on C-Span has been moving across the Universe at near the speed of light. Anyone listening within 100 light years would have already heard us.
Unless you want to shut down the electromagnetic spectrum, there is no way we can just hide on planet Earth and pretend we're not here. We make noise, lots of it... that's just a fact.
At the same time,we have been listening for over 30 years now, and we haven't heard even one sign of intelligent communication. If 'they' are out there, and are thousands or millions of year more advanced than we are, how come they don't make any noise?
As to some boondoggle project to blast signals at some hypothetical 'inhabitable' planet, I vote hell no. It's a waste of money.
That argument is addressed in the article.
