TLDR: why are we relying so heavily on cloud based search engines to organize hyperlinks? Local bookmarking tools could be so much better!
I've often thought it'd be great to have some kind of browser extension that used search queries to automatically tag and categorize bookmarks and threads of browsing history. Then, instead of having to manually put bookmarks into "folders", or think of tags, they'd be organized smartly based on the tree of searches and links that they are related to.
Here's a more concrete example: Say you searched for "curry recipes". You click through a number of different pages, finding one you like. When you bookmark it, bookmark would carry that "curry recipes" metadata, and be more searchable in that way.
A more complex example. Say you search for "gravitational force", and end up reading part of a blog post, then clicking through to another page and another. The third page is really interesting. So you bookmark it. Since the original search of "gravitational force" was the seed of finding this third page, that query would, by default be associated with the bookmark, even if it's not directly related.
This could be extended with all kinds of interfaces. For example, your browser could display a kind of "tree" of recent search queries at all times, which could be pruned, cleared, or added to at any time. A new tab would by default inherit the old tab's tree. Bookmarking would flow naturally from this, as a way of snapshotting a given thread of browsing.
Another, more complicated option would be to bookmark actual threads or trees of links themselves. A cluster of related wikipedia pages could be bookmarked together and traced to the search query that initiated their discovery.
If a page was implicated in multiple bookmarked clusters, it'd be easier to find it in your local bookmarks.
The upcoming annotation standard could end up being a great tool for extending this idea: https://hypothes.is/blog/annotation-is-now-a-web-standard/
