Well, I can say that the crowd funding process for my series, The Silver Ships, was a learning experience. For me, it was not very successful, only about 11% of the target was collected. These are the points I might share:

• Don’t use crowd funding for writing unless you have an established history as a published author.  Crowd funding appears to work best for products, inventions, software, etc.
• If you have a large established social network, this may make crowd funding for a fiction or non-fiction novel possible to a limited extent.
• If you do decide to launch a campaign, you will receive dozens of offers to promote your campaign. The three groups that I invested in were absolutely worthless.
