The ability for me, as an individual developer working in multiple countries across different time zones is priceless! I can work at my own pace without having someone else's schedule dictate mine - which has been one of our biggest challenges since we started using this service (we're located all over Europe).
It would be great if they could add more languages but otherwise it works perfectly well so far!! We've solved many problems that were previously very difficult or impossible due their lack-of integration into other systems such us Salesforce & Slack/Telegram etc..
