Yeah, duh, that's what he means....I mean, it's just a page with Twitch embeds on it? Don't really see how this is a special feature.
Pretty sure you can embed Twitch here too.
Unless of course you mean that page auto-embedding the streams of members with accounts linked to Twitch.
What's wrong with member promotion? We should be looking to support fellow Era streamers, or at least it would be cool to have the option to do so like this.
