Hi @juhli,
Adding information to one's profile is optional. I find that people add details as they meet other members and become comfortable in the community.

I noticed from your profile that you are not following any specific groups or pages. By following a group and/or page, you can tailor the type of discussions that are included in the Daily Digest email that you receive from Connect. This helps you follow discussions and blogs that interest you.
You can choose Groups to follow here: https://connect.mayoclinic.org/groups/
And Pages here: https://connect.mayoclinic.org/pages/

Here are instructions on how to follow a Group or Page https://connect.mayoclinic.org/get-started-on-connect/#how-to-follow-group
