My experience with this is very, very different. I think Google search has generally become much worse than then, although other search engines seem to be at about early 2000's quality level.
Even with the trend of personalized search, bookmarking still has a place because it keeps the act of sharing web content social. Right now, there isn’t a way to search through the web pages curated and recommended by a friend or an expert.
Edit: Reddit is a possible example of the above, but what I meant is an automatic curation of search to niche ness or specificity of people.
