I noticed that too. I was wondering if the last person to donate did it on purpose.
We could try that. $200 at 27px high is $7.4 per pixel. Do you think it would encourage people to break donations up? We lose more money to Stripe that way, but it if encourages people to donate more, then it could be worth it. I also wonder if it would cause donation fatigue, like the damn thing just won't stay full, so to hell with it.
Just spitballing an idea here... what about Patreon? We subscribe to give you $x/mo, and you keep doing Hubski if we can get to $2500/yr, or $215/mo? It's a piddling amount to gather via Patreon (some artists pull in several grand a month), and it is a unique funding model, for a unique community, that could result in huge benefits to you personally if this whole Hubski thing works out. ;-)
