Is it really a wise idea to broadcast our presence to the universe? I mean, do you really think those able to receive the message would visit us for non-selfish reason? Think it better to lay low for a few more centuries. The last thing I want is a bunch of liquored up aliens doing a drive by past my planet.
If you mean that as a serious question, I'll give you a serious answer - no.

I suppose it could come down to that, but while we do not have technology to go star hopping and others potentially do, it's just better that we keep a low profile until we can.
We're at the bottom of a gravity well, so minerals are probably not valuable enough for someone to want to wipe us out for that. Certain biochems might be though and the first aliens to visit us could well be in search of new recreational drugs.
For whatever reason, I've been thinking a lot about alien invasions since around November 2008. Sigh.
