Not to criticize you in any way, but I've found that asking me for financial support works in some cases and those are because I felt the "humanness" of the creator. I remember this author that put up a video of her unboxing first batch of her newly released book (and being excited about it). The person went from a name on a webpage or face in a video to a human being immediately (in my mind). I don't really have the words to precisely describe what I mean.
That's all true but it means that you need to market your person, become an "internet personality" just to collect donations on something technical that you built
It works, true, eg Andrew Kelley is funding his Zig work that way and it's pretty amazing to see him ace it. But damn you gotta be a particular kind of person to not get extremely stressed out about that prospect.
I don't think it's mandatory to become a different kind of person or to market yourself in extroverted ways. I think you could get that effect with subtler things. I guess we often treat our works and online presence (as in open source or open access projects) as functional non-human items. Maybe if we saw them more as extensions of the author...
Ah, you've beet me to it skrebbel. :) I actually wanted to write something like this. It's really hard to be what you are (in my case - a very introverted and private person), give something valuable to the world and actually live from that.
That would be a beautiful life, really.
p.s. Not saying there are no people who didn't manage to pull it off, but I'm pretty sure those people are exceptions rather than the rule.
