@steemitqa from my perspective, I think Tippy has a much greater potential than Zappl. While I love Zappl (and donated towards it) and think it's future is very bright, I believe Tippy has the potential of becoming a much larger game changer for Steemit. Hopefully after @kyle hacks out Tippy v1, he can work to make a subscription like service through Tippy which people can opt into to support their favorite content creators. That would be incredible.
