We're running http://androidweekly.net and http://swiftweekly.com?

It was roundabout 5 years just editing and making no money. Now it's making money - but just a side income.

1. Content is king! 2. Start to build a community (if you link someone in your newsletter just ping him on twitter). 3. Go to community events.

Doing ads on Facebook and Twitter actually didn't work that well.
