The geek chorus
Every sub-topic has its geeks. There are geeks who are into pencils, Bob Dylan, futures pricing. There are geeks who obsess about Wikipedia edits, journalism and even geek culture.
When you do something that matters, it will probably matter to the geeks most of all, and the geeks will speak up, dissect, analyze and perhaps extol or criticize. It's a symptom of doing good work.
The question is this: will you spend a lot of time listening to them?
The more you listen to this audience, the more likely it is you will delight them.
On the other hand, if you want to reach a much larger audience, you have no choice but to figure out when to ignore them.
