Awesome roundup, thanks for the shoutout :)

We soft-launched ZenHub.io [1] on Betalist in early November and have been very happy with the results so far. Several hundred high quality users who are engaged, providing feedback [2], and inviting their team members. The tweet-storm whipped up by Betalist was cool too :)
