Plain old hits counters are boring. If you are a webmaster running a website or blog, you need a flag counter, which will count your site visits and display country flags and visits against it.
Not all blogs post their number of subscribers. Pretty obvious the blog with high number of readers and subscribers will publish its subscribers count to let the world know. What if your friend has got a blog and he/she is boosting about the number of readers/subscribers the blog has got? Now there is a way to check the number of readers/subscribers any blog has got and FeedBurner (Now associated with Google) will tell you that.
