Not sure, but perhaps this is one of the reasons why there are so many complaints about wrong personalization of compact links.
Given that I know Norwegian Bokmål
When I visit an article at nowiki
Then I expect the preferred weight for nowiki to increase
Given that I know Norwegian Nynorsk
When I visit an article at nnwiki
Then I expect the preferred weight for nnwiki to increase
If I have one browser with one tab this works, because I will use CLL to navigate between the sites. If I use two different tabs I newer navigate with CLL, so how is the preferred wight increased? Is it increased at all? By opening two tabs in Chromium in incognito mode it seems like a tab with nowiki isn't updated with Swedish links when i open another tab with svwiki.
Could this be the reason why some users claim they don't experience any personalization?
