I really like Flow, and dislike the English Wikipedia's current talk page system. I have witnessed a lot of instances where users are confused about the talk page system and end up using it wrong, many times resulting in their opinions not seen by the relevant people, nevermind considered; and other times resulting in historical discussions being difficult to follow without using the page history to see who said what when.
I think Flow is better for new users, and is a good way of encouraging their input on Wikipedia, thus making Wikipedia grow as a project - at the very least by making it easier for them to submit properly filed edit requests. Although I have a personal leaning towards the freeform style that Wikipedia's talk page system allows for, I want to see Flow succeed for the greater good, and I think there are many others like me. I'm glad to see it being implemented in other Wikimedia projects and I hope that it will benefit them greatly.
I recently noticed that the English Wikipedia has had its Flow extension uninstalled because of the halt in development.
What can people like me do to help Flow succeed? Is there a donation page especially for this extension? Could there be one next time development starts? Is there a bounty program? A box to tick showing our support?
