-- What is the difference between marking something as shared by clicking the 'Share' button at the bottom of a post, versus marking something as 'Starred' and then making sure that the 'Starred' tag is marked as 'Public' from within Reader's preferences? -- Why doesn't typing a Question-Mark (?) on my keyboard show the on- screen keyboard shortcuts list, as it does with Gmail? -- Is there anywhere in Google Reader where I can browse popular feeds, or something like the Bloglines 'Top 1000 Blogs' list? -- How long do posts that I've starred, or marked as shared, remain in google reader? -- I think I might be missing something when it comes to tagging a blog post...Is it correct to assume that if I want to tag a particular post with, hypothetically, a tag named "Digital Audio", then I would actually have to click on the "Add Tag" or "Edit Tag" button at the bottom of a post, then manually type in "Digital Audio" every single time I want to tag a particular post with that tag? If so, is there really not a way that I can simply drag a post onto a tag that appears in my subscription list? If not, doesn't this seem a bit tedious? What if there are 10 posts in a single feed, one appearing just a couple of posts right after the next, that I want tagged with a particular tag...I have to manually type in the tag title for each and every one of them?
