For Links/Bookmarks I use Google bookmarks - https://www.google.com/bookmarks/
which surprisingly has not been killed and looks like might be left alone by Google.
Other bookmarking services delicious.com & posterous etc all died in due time.
By using browser extensions and a 3rd party Mobile App. I am able sync/store all the links. Though I would love to be able to sync bookmarks to my org-mode notes. Looking at org-capture now to see if that could possibly work (https://github.com/alphapapa/org-protocol-capture-html)
