I think they try to do this to some extent with "perks." As a crowdfunder and crowdfundraiser, I can see a divide between people who donate bc they want emotional pleasure and people who donate bc they want to receive something. It should be possible to segment patrons to address different donors' desires. Maybe if you're a music patron seeking stuff, you get options to buy particular tickets/seats or are the first to get songs or limited editions or something. If you're seeking status maybe they put your name somewhere on their website or send you a special Facebook logo, etc.
