Google Reader

So in my quest to revamp my life, I started using Google Reader last week.  That way I don’t have to click on each and every one of my blog roll links to see if you have updated your site.  It has been a real time saver and probably delayed the inevitable carpal tunnel.

Anyone else use it?

If so I have two questions:

1.  I have subscribed to others but with an RSS feed how do I determine  how many people (and better which people) have subscribed to me?

2.  I know you can separately subscribe to someones comments separate than the post, but is there a way to set up google reader so I see the post and the comments all together?

Inquirering minds want to know.
