Recently my friend suggested, writing a bitcoin related blog, and monetize it with bitcoin advertisement networks is also a good way of growing bitcoin. I guess lots of blogs earning thousands of dollars like this. Planning to execute this method soon.
I see that kind of method is really not a wise move today. Time, effort etc. Nowadays there are lot bitcoin related blog with some nice feature and layout but still hasnt getting any much visitors.
People like to stay and read here in bitcointalk than in newly made bitcoin related blog.
