Software sits on the shoulders of giants.
Buttondown is a tool that simply would not exist without the gargantuan effort of many, many open-source projects, the vast majority of which are drastically underfunded relative to the value they provide.
I've committed to donating at least 10% of Buttondown's profits to the software that enables it. This is a relatively low number in absolute terms — I'm certainly not changing anyone's life — but I think it's still important.
I've finally pulled together a document for tracking Buttondown's public donations, and you can follow it here.
(I haven't pulled it server-side, like I did with my running costs, because I anticipate the data being much more boring. But if that changes in the future, I'll certainly re-evaluate!)
An earlier version of this post incorrectly stated that we donated 20% of profits to open source. This figure has been corrected to "at least 10%".
