How can I keep count of people reading my blog?

Keeping track of traffic on my site is not an issue but most of my readers access my blog through RSS feeds. I haven't found a good way to figure out how many people have subscribed to my blog and how many read each article. Any tips would be appreciated.

If you go to www.feedburner.com (it is free) , you can set up your blog/rss feed with feedburner and it will track the number of people who subscribe to your feeds for you.
