Twitter recently announced it'd be publicly showing the number of Bookmarks a post has. [1]
This led to a discourse around whether or not Twitter would continue revealing more information, particularly "Who bookmarked this"
On WeWrite, this will never be ambiguous. Since Bookmarking on WeWrite isn't technically a feature, but rather it's encouraged that Users use a custom Page for Bookmarking, then it's obvious that Users will have control over who is able to access that page, via Privacy settings.
So instead of hoping and praying that Elon Musk doesn't expose your bookmarks to the public, you'll always have control over who sees what in WeWrite.
