I personally don’t think it’s that. I’ve been thinking about blogging and how sometimes it’s perceived as being maybe a bit showy, and I do get that a lot of blogging isn’t necessarily always telling the audience something brand new and innovative, but for me it doesn’t have to be.
I think that for a lot of service teams communication is absolutely key and that *always* comes with issues. For a new team getting into the habit of “overcomminicating” means that blogging becomes a discipline and helps with documentation. I believe it really helps to form a cohesive team and forces teams to think about how they can “work in the open”.
For established teams I would say it’s something to help prevent complacency from setting in (and possibly to keep people aware that the team are still there and still working!)
