Firefox Sync + Firefox Bookmarks + Firefox Addons for managing native bookmarks + https://github.com/WebMemex/webmemex-extension for indexing + custom code to generate static web pages with pure JS search with content out of bookmarks + I send interesting links to my friends if these could be interesting to them via email.

Do not use proprietary closed source solutions.

UPDATE: For something more importatng I use gitlab/gitlabe pages(my works usually) or syncthing (copies)
