I do almost the same thing with pocket and GitHub. I use Pocket to save articles. I slack in tagging them but sometimes sit down and tag all the untagged items at once. About going back, I have recently started taking notes from them in a Github readme so that I can just go back to the readme and find the appropriate one to see. I have only recently started doing this as the number of saved articles have become overwhelming.

It works out well, if not perfect. Usually, articles are not to be re-read completely, only the important parts or the gist is enough.

Please let me know what are your thoughts regarding this. May be we will both find a better way to deal with this.
