A new service on the web says, "Aliens Love Blogs Too!" Blogs In Space
calls itself the "first entity to allow everyday bloggers to transmit the news and thoughts of an everyday person into space." They say that at no charge to users they will beam your blog entries into space using a "powerful deep space transmission dish."
They do request that you not use any language that might upset an alien species. (We wouldn't want to start an intergalactic war.)
