I can see that has worked pretty well for you. Short thoughtful and engaging discussion posts do work pretty well.

I did make the assumption in this post though, that the writer wants to write in long form (whether because it's a detailed guide or short story, it's something that a 30 character post can't tell)

It should also be noted that these suggestions don't work if the reader isn't interested in the content to begin with as well.

Thanks for sharing your insights.
