Is your blog idea actually big enough?
I answered this original question on Quora:
How much potential does cricket have as a niche for my new blog?
I decided to expand the answer a bit.
Picking a niche is the scariest part of starting a new blog.
You worry that if you go too specific—like "cricket"—you will run out of readers before you even start.
But before you scrap the idea, look at the data.
Right now, the cricket subreddit has 342,000 members.
Think about that number.
That is enough people to fill the Melbourne Cricket Ground (one of the largest cricket stadiums in the world) three times over.
That isn't just a "hobby." That is a massive, pre-existing market waiting for content.
Where people flock is where energy lives. And where there is energy, there are people you can serve with your work.
The audience is already there.
They are already obsessed.
The only missing piece is your commitment to show up for them over the long haul.
If you love the topic, the potential is waiting for you.
