I think karma in relation to up/down vote of posts is a good thing.
The total karma of an account isnt interesting for me, but other users may be more interested in it.
Best solution in my opinion would be if it is handled instance based. If one instance decides to show the total karma of a user its ok for them another instance might decide to not show the total karma or even completely hide up/downvotes.
So every user can find an instance that alligns with his view on this matter.
But the political parties have a lot influence on who is getting the (very well payed) jobs so its not like its really independent.
