Congrats! I have also thought this is a great way to give back to others. Give a paid sub for every so many you gain. I know paid subs are rare but when it happens, or when we can, I know spreading the support back around makes a difference. I think of it like if we were to buy a book from an upcoming author for every so many books we sell, and recommend it to others if we like it; what would happen if more people did the same. It builds a community of support
