Etiquette

One of the most powerful aspects of the Internet is the lack of walls.

This creates an opportunity for vast groups of people to connect.
It also creates a useful and convenient excuse for being rude.

Your challenge as a blogger is simple:
To create useful, relevant, and unique content for your niche.

Being considerate of others augments the value your content contains.

This doesn't mean to subsume your voice into political-correctness.

But it does mean that your target audience is bigger than you know.

And part of your challenge is to honor that core audience.
