Like you, I have wanted a place to really save my thoughts and the thoughts of others (a la Evernote). Additionally, for folks involved in social media sharing, an easy way to share selected work (a la Buffer).

I love the idea of Medium’s highlighting, but then what? It is stuck in Mediumland. What about a blog I read elsewhere? What if the author puts into words the thought I have been pondering? How can I easily save that or share it (Highlight + Share + Buffer, process)?

My current process of saving it to Evernote still requires me to remember/be reminded to follow up and take action next time I am at my computer. Then, like you originally mentioned, manually add the original URL for context.

I suspect there is a need for a tool that works across mediums and operating systems — perhaps a browser add-on that can integrate these various services together and make it easy to save, share, and curate the amazing content people publish.

Food for thought, if someone out there wants to take this on.
