I agree, but this is not an inherent difference of the open web vs. a walled garden, only a difference of implementation of the software involved. Indeed, the developers of the Web and its browsers were aware of this problem, and they though that they had solved it, using something they called “Bookmarks”. Now, as implemented, bookmarks may not be easy enough, and there have been other ideas, like RSS feeds, which tried to improve upon the idea. Just don’t think that this difference is inherent and set in stone. New features could be developed.
