How to find all projects that a resource is "Following"?

I don't think so, but you can have resources add themselves as reviewers to projects instead of followers (more functionality) and in the Layout add "Reviewer of Work Items" as a related item to the User View.  That way when you go to People and select a user, you will be able to see all projects where they are a reviewer.

Has there been any updates on the ability to create a report that a resource is following? Also is there an ability to run the report as editable so the resource can be easily removed from following the project?
