If you get a nice website, and a tech demo, sometimes crowd funding can pay off.
You really need something to show them first though. Most of the Green Light games I am seeing on steam are the ones that have a nice presentation, and a semi-playable tech demo.
I am going to go the Desura route for my first solo project. If it seems like a popular game during the alpha funding phase I am going to invest the $100 to submit to Greenlight.
The way node-webkit is advertized to make cross platform games, should make a great splash in the Desura community. Most of the "Big" indie games I see there have *nix and sometimes Macintosh support.
Windows-only games seem to get trolled and flamed more by the community.
There are other ways too like panhandling your community with a "Donate" button, Kickstarter, and a few other community funding sites.
i suggest funding yourself for the first little while. Then come out of nowhere with something "Eye-popping" and hopefully fun to play.
People seem more likely to fund material things rather than concept art, promises, and dreams.
This is going to be my first solo comercial game. So please take my advice as a grain of salt.
