Let's not resort to mob mentality, please.

I think it would be perfectly valid to write something along these lines:

"Hi! I just found out about ArtistShare.com. Looks like a great site! Unfortunately, the way I heard about it was that I learned of the patent suit by its founder, or a licensee, against Kickstarter.com. In protest, I will not be participating on ArtistShare. Just thought I would let you know. Have a great day!!!"

That's the sort of thing that only hold weight if you ever intended to use ArtistShare.com.

It's like me threatening to boycott Time Warner, McDonald's or Barney's - I'm not their customer, and I never will be, so what do they care?

I'm only one customer, but I'm clearly in the target market, as I've contributed to three projects on Kickstarter.

You're right, it would have been useful to point this out.

Letting your opinion be known and asking others to share their's as well is not mob mentality. If we don't let people who operate in this manner know that there are many of us that are against their way of doing business, how can we expect things to change?

I doubt a patent troll cares about what people think.
