Thanks for the mention! (I'm the founder of Blogalia :) IMHO, greaterskies.com is interesting as a project, but: - I don't think anyone will pay for simple visual star charts: there are free sites, free desktop programs and free tablet/mobile apps out there. - If not for visual, but deep sky: there is 3Atlas from José R.

There are some forums, like cloudynights.com (or http://www.asociacionhubble.org/portal/index.php/foro http://www.asociacionhubble.org/portal/index.php/foro in Spanish), but this are mostly for dedicated observers. My 2 cents.
