user6870: Is there (or can there be) an option of following the activity (questions and answers posted) of particular forum members? It may be helpful in educating oneself with the thoughts of particular members who we feel are likeminded or whose thoughts are to our liking. It will also be helpful to new members (like me) for tracking and learning from the past activity of these members. 

user254: Yes.
Consider an answer like this one for example.
The user name of the author of that answer ("Andrei Volkov") is immediately below the answer.
That user name is a hyperlink: if you click on it you will see that user's user profile, where you can choose to see their profile or their activity.
There are links on the Activity page from which you can list all their questions, all their answers, etc.
