Ars Technica:

Sometimes the end of funding is the beginning of a slide into radio silence, which ultimately turns into few or no backer orders fulfilled, and no satisfactory explanation for why the project didn’t pan out according to the orderly delivery schedule the creators promised.

A project can go off the rails and fail even after its funding succeeds for a number of reasons. There can be unforeseen costs, or design problems, or a team member quits or fails to deliver their part of the project. Often, when a project skids to a halt, the final updates are obscured from the public and sent only to backers, which may be part of the reason failures are often not well-publicized. Occasionally, backers who receive them pass them on or post them publicly on forums, which is as good as it gets in terms of letting the outside world know a project did not ultimately pan out.

I’ve been burned by a few Kickstarter-type campaigns. Rule of thumb is to assume the money you are handing over is a donation – if you get something in return, great but don’t hold out a lot of hope. Granted, the majority of Kickstarters complete successfully but there are still plenty that don’t. Caveat Emptor.
