@mark I understand your point but I want people with less resources to also be able to run their own instance. It's hard to know what is the right answer. But thanks :)
I like Chris's suggestion of pay-what-you-want / tip jar, but in the meantime I can upgrade my instance even if I don't "need" the extra oomph. I've avoided that so far because I've worried that larger instances have higher costs, and so the delta wouldn't actually go to you.
@dcreager Well, if you don't actually use the resources there is less costs for me. In terms of app processing server resources I do allocate per size of the instance but things like database or media storage, backups I can control the resources needs and so only allocate as needed.
In terms of work for me the smallest instance gives me as much work as a large one if there are no support requests :) Large instances normally do have more support needs.
This is a tiny instance.
