You're too kind. :)
The full story is a bit more complex, but, yes: my wife and kids and I are sacrificing financially so that I can work full-time on Gittip. When I work on Gittip part-time, it flatlines. When I work on Gittip full-time, it grows. I'm grateful to have consulting work available to me, but at this point I'm so wrapped up in Gittip that I really just can't concentrate on other work.
I'm netting almost $200/wk on Gittip right now (thank you!) and if that gets to $800/wk by the end of 2013 I'll be the happiest kid in America. Gittip will be almost born. I'm encouraged that that's only a 4x increase.
That said, if Gittip works for me it'll only be because it's working for many other people as well. My focus in the next month or three is going to be on roughing in the features like communities and projects and funds and friend-finding that will help Gittip work for everyone and will get money moving through the system. Then the focus will shift again to building up the contributor community around Gittip, once the pieces are in place to actually get people paid for working on Gittip.
Gittip is almost a year old. If it's going to fly, we'll know within another year. I'm hopeful! :D
