You can't see all the members, but if you add the tracker, you will be able to see a selection of members who do.
If there is a member that you are interested in specifically, you can check their profile, and if they have a tracker, and it's set to public so everyone can see it, you can view it that way.

Below the tracker on the right, you can see some of the most recently updated trackers.
Or if you click Browse (above the Print & Settings links) up at the top, you can browse through a bunch of trackers.
To see some of our public Mood Trackers, check out the Mood Tracker Gallery:
