My stuff always gets upvoted or downvoted. If I see even one of my comments not voted on, I discard the account and move on to a new one.
PG et al do not value your time and contributions, so it's best not to get hung up on karma or handles. Say what you want, and change accounts regularly.
All I can say is if your startup doesn't work out (which I hope it does, I love the idea) you could probably get a mint for the cherry.com domain name.
Dreamhost suckered me that way. A few years ago they offered a limited time special anniversary discount (only 11 days left!!), however, the anniversary sale was still on months later and there were only 11 days left!!
I will never, ever use them again for doing that to me.
