Awesome, this is some superior reply giving a very good insight about your industry! Thank you! My question is, is there something specific about the photography vertical which makes all the sub-niches so lucrative? For example, email newsletters: is it so popular because of the heavy amount of photography tutorials, articles, etc. available on the web and only a few other industries would experience this kind of demand in newsletters? I think photographers are the most heavy consumers of online tutorials and articles along with hackers and designers.
