> Code review I do using local tools (the editor) face to face, again not sure you need an online service for that unless you're a larger company with lots of developers coordinating (in which case it becomes pretty essential).

I mostly like online code review services because they offer an audit trail and semantic history that's easier to navigate than email. And of course, to let CI automation check tests, coverage and lint. Not because I don't trust my coworkers, but because otherwise I would forget to run tests and lint myself.

Lots of different ways to do it, and of course github and online code review is tremendously useful to people, particularly on large projects with lots of collaborators, and where a history of reviews is required.

For lots of small projects though, it's perhaps not as necessary as people think. I run tests and linting locally on save and don't really use the code review/CI features of online hosts much. That won't suit everyone of course, but it is one possible path.
