Yes :) Idk if she mentions it in the article but I learned in school that här/var is a co-ordinate, and hit/vart is a direction! Should work with the others as well.

And also similar to "där" och "dit"

Vart han går? Han kommer hit. Var han är? Han är här.

The Local unfortunately deleted all of those posts a while ago. It's a great shame: they were a tremendous resource.

As for the actual question, här is a place and hit is a direction. Hence:

• jag går här = I am walking here, as in: I am walking in this place
• jag går hit = I am walking here, as in: I am walking to this place
