Re slack... good discipline on our part does make it easier to catch up even after hundreds of messages are posted. We do try to organize discussions using slack threads so that it is easier to follow a particular topic. This doesn't always happen and as I noted, requires good habits.
We have also applied the practice in slack where there is a discussion worth recording for posterity to open an issue, send an email to the dev list, and make sure it's not only recorded in slack. We do have a channel just for PRs on slack, and while we have several channels, we mainly use the general channel for all discussions. I think this was worked well to keep all topics widely visible but that is only my opinion of course. Weekly summaries if they can be automated could be a nice way of catching up. Perhaps an opportunity to use OpenWhisk itself to generate the digests, perhaps summarizing the PR activities and commits to start. -r
