I made a small change to my site, so that bookmarks don't show up in the main feed unless I've commented on them. I tend to bookmark a lot of pages, so this will keep them from clogging up the home page. Plus, it clarifies the difference between bookmarks and boosts/reposts. Now, boosts are posts I don't have anything to add to, but still want to show up on my home page. Bookmarks are pages I want to save for later, but may have something to say about once I read them.
