The timetables for internet crazes, their backlashes, and the backlash against those backlashes are getting increasing shorter.

You should probably only support kickstarters that have demonstrated some material or that you trust somewhat personally. I've backed two albums for previously-dead Christian ska bands (lol) plus the Wasteland 2 kickstarter. I only felt really comfortable with one of the two bands, but I figured the odds were pretty good the others would pan out. I feel bad for the people asking for very small amounts of money who get even less, but them's the breaks.
