Trying to convince me to set up a subscription upon any visit (and especially upon the first visit) isn't gonna be very effective. It requires thought and some calculations.

"Liked it? Pay me $2" is a way more simple decision to make. If I make it to the end of your content and see a PayPal.me (or Ko-fi) link, there's a reasonable chance I'm going to click on it. I can't say the same for links to Patreon.
