I joined the @vimm dev team partly because of my distaste for Twitch's opaque ToS and the way they treat their streamers who aren't partnered.  Vimm currently takes a 10% beneficiary cut from streamers, which we use to fund our servers.  We're researching a means of selling Vimm Gems, our own token, via our own online merchant.  We will take our share, but our goal is to be as transparent as possible with what we take and why we do it.

Sure, we're not perfect, but dammit, we try!  If we can get more people to drop in, stream with us, help us grow, we could rival Twitch.
