I think this post should answer this quesiton for you. :) EDIT: Reverse TL;DR In addition to paying for servers, we buy stickers a couple of times per year, send them to people, and typically buy a few meals, drinks, and t-shirts. We might also include occasional travel expenses in these costs, but Hubski meetups feel too much like vacations. Hubski has always run in the red, and the money has come out of our pockets. This isn't an ideal situation, but it is a bearable one. However, there may come a time when our situation is not so bearable, and we thought it would be a good thing to be clear about where we are at. We have set the 2016 funding goal to $2400. Assuming we can bring our server costs down as planned, $2400 should enable us to pay for our servers, and leave some money for stickers, swag, meetups, and some room for an increase in server demand. Of course, there's more content, commentary and jokes within the post and replies in that link above, but this is the fiscally relevant portion from mk's post. Are there any public figures regarding the specifics of Hubski's operation costs?
Currently, Hubski's server costs are $212/mo. That equates to $2544/yr. These costs are too high, and reflect an inefficiency of the Arc app. We are currently working to correct this inefficiency, and once this work is completed, we expect that out costs will drop to $116/mo, or $1392/yr.
https://arclanguage.github.io/ref/ I do not recommend learning it. If you want a Lisp to learn, Racket is a good choice. Arc is a terrible, poorly documented, poorly supported, unreadable language, whose primary goal is to save characters at the cost of comprehension. Which is lunacy. Characters are in far greater supply than comprehension.
if memory serves... Arc was an offshoot language that Hacker News was written in. When mk first built this place, he did it based on HN code... which was in Arc.
