I have a hard time believing there’s any one or more than a literal Hand full who are so diligent as to actually do this for every site that is good enough. It’s a common talking point though as if it’s actually a practice that would could be common
That is what I said is a common trope, but is an inconvenience, hard to remember, and likely not done by many if any people. You don’t appear to do it either.
Same with your tip jar. You say small sites which isn’t wrong. However in your case you’re only topping the same 2 dozen sites you go to.
Not every site or app has the same engagement necessities. If a site can be visited much less but is very helpful, it’ll likely get much less tip money than a less helpful but regularly visited site that gets your dopamine going. I’m not saying this as fact. It’s something I believe could be true with no backing.
