I like that this helps us manage our PRs more efficiently in real time, rather than having to wait for them to go through Github's review process. It has helped us increase our overall participation and collaboration within the team. Sometimes it takes quite some time before we can see the changes take effect after a PR is submitted. We are currently using Reviewable as part of the PR workflow. Using this service helps us keep track of all the comments and suggestions from peers as well as internal stakeholders.
