github vs. trello

Github

Pros

  • Pull requests are the thing for getting dev done, seeing what others have done, and discussing it. I love pull requests.

Cons

  • Developer-centric workflow that doesn't provide much value to the rest of the business, because it has no interest in that at all.
  • Not particularly flexible organization of anything, milestones are a bit clunky to use, so it's mostly just labels.

Neutral

  • Individual issues are a pretty good place for discussion, but not a killer feature at all like PRs.
