Det smarte var om du hadde gitt beskjed om at Kvinnherad skulle takast av lokale folk manuelt. Ved å sette nokon som ansvarleg på osm.wiki/Import/Catalogue/Road_import_(Norway)/Progress så ville det ikkje vore problem.

What class it should have is a matter of opinion :)
The wiki is to vague IMO. To open to what each mapper feels like, which again creates a very inconsistent map.

Giving a gravel road with a width of maybe 3m and no sidewalks a tertiary class is to much IMO.

Suggest adding max length and weight if you really want to keep Dala- and Austefjordvegen at tertiary.
The segments in Bjørnafjorden has a max length of 12.4m and the whole road is max 32t.

Please read the wiki for Norway. Tertiary is used for roads with scheduled bus routes.
Making local/rural municipal roads tertiary will cause through traffic that should not be there. It is valued quite high in most routing software.
These roads are not wide enough to really support large vehicles.

Road class is not based on quality for secondary and up to avoid a complete mess.

I see you've set several branch roads as tertiary. This is not correct unless it has scheduled bus routes.

Why did you set Dalavegen and parts of Austefjordvegen as tertiary? Do this road have scheduled bus routes? If not then it is not a tertiary.

Why was this added when there is already one in the database?

Ville brukt unsigned eller local ref på Ryfylkevegen.

Please do not use Bing in Norway to map stuff, it is terrible. There are several sources available with better data quality.

Oops! Didn't change the key on this segment after conflating tower heights. Thank you for pointing that out. The key is from the Norwegian SOSI standard.

Ver snill å ikkje bytte klasse på Hulkavegen. Var alt ein note på den som du ignorerte. Bjørntvedtvegen har heller ingen busstrafikk i dag. Den er rekna som lokalveg med farshumpar.

please do not attach roads and buildings to landcover

You need to be careful with editing landcover using iD editor. It is not very good at dealing with multipolygon relations. This is more advanced and should be done with JOSM.

Vegane i Nygårdsparker er vel ikkje rekna som gågate? Lurte på kvifor du endra desse til highway=pedestrian

Du er klar over at det vil lage masse ekstra arbeid ved ein eventuell import av N50 i nabokommunane sant? Heile corine bitane burde vore sletta.

Kvifor var dette nødvendig? Du har laga meir rot på grensa en nødvendig og rota til relasjonar etter dette.

Please do not add municipality road refs to the normal ref= tag. Use unsigned_ref= instead.

Vi er litt "på tuppa" sidan det er mange Pokemon entusiastar som lagar parkar over alt slik at dei kan finne pokestops? eller noko slikt.

Ser ok ut for meg. Om dette er definert som ein park av kommunen og lokale folk så er det jo ein park. Men name= kan nok bytast ut med description=

Please describe what you did and not just use a generic "minor mods" for all changes.

I've reverted the edit for you ;) You'd have to simply delete the new tags. The node was probably never moved.
There is a script that is run to check for new/updated addresses from Kartverket and a separate user account (add2osm) that basically do the update. For many office buildings there are multiple companies on the same address so it is best to add a new node ;)
