I expect it will move closer yet before all is said and done. E.g.: https://github.com/whit537/www.gittip.com/issues/316 https://github.com/whit537/www.gittip.com/issues/316 However, the primary distinctive is that Gittip is funded on itself, whereas Flattr is for-profit and takes a hefty cut. I don't see that gap closing anytime soon.
