Reddit is a really great way right now, due to the boost to Reddits rankings on Google you can find old Reddit threads that still allow comments in the top 5 on Google with very high traffic keywords.
I mostly use bookmarks for easy access to commonly used tools and documentation; however, typically, I suffer from the fact when I need to share a set of bookmarks, the browser support of export/import is really awful for both the exporter and importer.
I encountered it so much that I built a tool in the last few months to allow sharing of bookmarks natively in the browser. I didn't want to use a new tool to manage my bookmarks; I just wanted to enhance the browser bookmark feature with the ability to share bookmarks.
