Thanks for creating this!

One thing I noticed: I just wanted to buy you a coffee, but the help-me-stay-add-free button at the bottom kept moving away because of infinite-scroll :)

Regarding staying ad-free, I'd say it really depends on what your goals are and what your actual product is. I'm not a specialist (by far) but I'd first try to validate the market fit before trying to raise funds (Kickstarter or however else).
