These are great, but it's too bad they need to be so siloed. All of these applications are popular partly because they're on the _internet_ where we can link between things. I'm not likely to click a Medium link and then go find that item on my scribe instance (for example).

It would be interesting to find something similar to how you can choose which application will open files of a given type on your desktop. You can choose if web links should open with Chrome, Firefox, or Safari. What if we had a layer where you could choose which "application" opened medium.com/* links or youtube.com/* links? _That_ would be an awesome resource.
