Currently adding over 4k paid users per day. He reaches $1 million at just over 40k paid users. Factor in the userbase he's already been building for 4 years, the hundreds of thousands of Google Readers currently leaving, the millions that will need to find a replacement before July, and the last-minute movers on July 1st. I don't think server costs and a couple of employees will put him below a 7 figure income.
