What makes a blog influential?
Influence is often attributed to traffic and readership levels. But in reality, those are actually benefits that are symptomatic of something that precedes them.
How do we get people to pay attention to what we say in the first place?
Ultimately, a blog catches on just like any other idea spreads—it must somehow speak to people in a way that they want to hear. Your posts must fill a human need, and that will most often be at an emotional level, no matter how practical we think our subject matter is.
