Topics of interest

I think, that it would be useful if we can choose the topics of our interest to follow, read, tag, etc…

Looking at the running list of topics, we have to scroll down for my topic of interest…

It would be easier if we can sort of choose my topics of interest.

How can we do that… Does it require tagging, Or can it be done by the system itself…

All I m saying is that we need categories or a basket to drop similar topics of interest or topics related to biology …

Currently it is done by tagging broad area tag.
