Do you think so? I think it's popular and users have embraced it. There's examples on Facebook pages where you have to Like to get so-and-so-dj-mix, and there's also PayWithATweet which came out 2 years ago. There's also the email newsletter, which for a store might include coupons.
My belief is that things like books, music, and other content take time to make and users fully understand that. What Color does, however, is help consumers realize they can reward creators without necessarily spending money, but instead with publicity, arguably even more valuable for new artists/stores/websites.
Everyone I know equates those kinds of pages with phishing scams. For me, the problem is mostly about trust. Without the ability to examine the content beforehand, I have no idea what I'm promoting and as such I won't touch it.
Your service would need to curate the content and gain enough trust for people already burned to accept the risk.
PS. The styling of the 'Free Download/powered by Color' button is broken on my iPad (The 'Free Download' text is below the actual button).
I absolutely hate this. I will like something after I tried it and really did like it. Asking me to like something before I tried it is a sure way to lose me.
