Reminds me of TranscribersOfReddit[0] which is a great attempt at trying to make the web more accessible for all. Reddit posts get cross posted and those without visual impairments can transcribe the photo. Their bot is also starting to get pretty good!
Is there a name for companies that release their code under an actual free license, but charge for other things like support? Companies that come to mind are flynn.io or sidekiq.org (both of which were recently on the front-page).
If Discord can keep up the growth, things like stickers, emojis, and sound packs could pull in good revenue. Also, the gaming community is already used to paying for these items on sites like Twitch
