I see that in this platform tags are here to stay and that is fine. But the usability of tags now is redicilous. In a right pane I see most popular tags - totally useless for me. I think what we need here is;
View of all my favorite tags (which I bookmarked myself)
Ability to group tags (for example - all my tags of SCCM (CM) product)
Working with grouped tags, so I can easily jump from group to another.
Remove the ability to add multiple tags on one post - a post starter should use only one tag. Otherwise, it might create a spam behavior.
