Google Reader

I can't figure out how to share things on google reader.

I love reading what other people share.

I think it's fun and cool, and its google, so I inherently like it, right?

But why can't I share an article I read in Time magazine last night on there? why can't you put in a link? and why is the time.com subscription only for a top-ten version of the magazine/website.

These things don't make sense to me.

Please, someone, volunteer to show me the ropes. break it down for me.

in the interim,

here is the article:
