Another way to emphasize growth within the team and ultimately the business is to create a project for interesting articles, videos, podcast episodes, or infographics.
Then you can tag specific people you think might find value in it by @tagging their name or by adding them as a follower.
Following that, you can ask team members to set aside an hour every couple of weeks to review those resources.
If it works well, people should be interested in implementing and experimenting with what they've learned from that resource.
Finally, this eliminates mass emails and mass responses, which is always lovely.
