This essay lists what we can do on web, which is more powerful than you may expect. Of course the web has its limitation, but the web has its benefits too:
Perhaps the biggest advantage the web has over native apps is how quickly users are able to engage. All that’s between the user and your content is one click. No redirects to the app store, nothing download, and find on your home screen, no passwords to enter. This makes social media sharing especially effective. Every person who sees a Jambells tweet is as close to engaging with the app as if it were downloaded and installed on their home screen. It’s just one click. Not only that, but it can be one click from anywhere. Their grandma’s PC, or their little sister’s iPad. Access isn’t tied to their personal device.
