Google doesn't always find the thing I want, at least in the context of a bookmark, which is something specific that I want to return to. When I consult my bookmarks it's not necessarily to remember the broad strokes of a story, it's to read someone's take or even a specific line from an article that I only vaguely remember now that some time has passed, but suspect was really good. Sometimes Google gets me what I want, but often there are similar stories from larger sources that trump what I'm looking for.

Sometimes I feel like going back through things I liked (or have been meaning to read for a while) about a certain topic in bulk, so bookmarks with tags are nice. Querying Google to show me everything I've thought looked interesting about [x] won't work.

Sometimes you want something that isn't up anymore. Google has cached pages for lots of stuff but not everything. Pinboard will keep a copy of everything I bookmark.
