If that's all you're using it for, you'd be better of with Hipchat, which serves as a functional notification channel and from what I recall is free for <10 users. I guess Slack would be worthwhile if you're using it for multiple projects, though.

How your setup works then? Sounds like something that could improve performance of single dev.

I definitely plan to write about it on the journal (http://cushionapp.com/journal). I have channels for new users, Stripe charges/subscriptions, errors from Sentry, build notifications, and support notifications. I plan to also build some Slack bots that would help automate a few things.

Sweet, I am looking forward to it. Good job with the project!

Please do. I look forward to reading about the channels.

I see, that's awesome! Great job juggling everything to make this work!
