I bet what they all have in common is that they all used advertising in order to get to their position.

What kagi can’t fix is that most forums nowadays don’t exist anymore and moved over to discord which is also a big reason for worse search results.

For example I had a technical problem with a device of mine, searched for maybe half an hour on Google until I joined a related Discord. Searching there in the support channel and I found the fix for my problem. Would Discord not exist and all the content be queryable by Google I would have found my answer within seconds.
