I'm gonna do some exploring and write a blog post about this!
@hamatti Another option would be to have a shared web-based dashboard type of page that would list latest blog posts from those 3rd party blogs (and other feeds). That way people wouldn't even have to maintain their own feed readers, because latest posts and links could be read from the central location.
@autiomaa Slack supports RSS subscriptions too so for teams using Slack, the "easiest" way would be to just subscribe there but I feel Slack is the wrong place and the feed would just create noise and get muted.
