Interesting. I did the same within just my team. We used Confluence to publish those, describing accomplishments of every IC. This initiative was started to appreciate the work of the team, so I still was concerned if anyone were reading those reports apart from my team, but I never had a question from the Steering Committee "what all of these peeps doing there?" since I started.
Question: what the format you have used (number of words)? Kind of a release notes? Was anyone actually reading those?
