The only way to share your Google bookmarks is by creating lists. By default, lists are private, but you can share them with other people and make them public. The nice thing about public bookmark lists is that they're searchable and you can find them below your Google Bookmarks search results.
When I searched for this blog's URL, Google Bookmarks returned a list with useful Google sites and Google-related blogs. I could also enter some keywords in the search box, but the results aren't always relevant.
