It was in the summer of 2008, three years after Google launched Reader and had at least 5 million users, when I decided to write my own RSS reader. There were just so many features I wanted that I knew Google would never build and for some strange reason I thought I could make money with my own opinionated take on a news reader.
Then at 4pm on March 13th, 2013, I got an email from Nilay at The Verge asking if I'd heard the news. That was a difficult month as I scaled (and wrote about scaling[0]), since by then Google Reader had 10 million active users. After Reader was sunset, about 5 million found their homes on the news readers that remained.
It's strange to think that naively competing with one of the big platforms paid off, but there's plenty of companies that did well in the wake of a giant choosing to ignore the ecosystem near their feet.
