Hello Elias,
I love some of your suggestions. I'd like to apply them to a new company I've started - Astro Publications. I publish a beautiful line of astronomy greeting cards that I launched for IYA as gifts, fundraisers, and for clubs as I saw a need to have cards available featuring real images of celestial objects taken by some of the best astrophotographers. Would the avenues you discuss be applicable or more for social networking?
Regards!
