If you always wanted to have a live activity feed for your blog on blogger then you must check out cool widgets from WowZio
Just Say Create my widget now.
On the creation page enter your feed url or simply your blog url.It will automatically get posts from your Blog and then just click create my widgets.
It will create many widgets for you but my favourite are Live Activity Feed and Tag Cloud.
I am using same widgets in my Blogger blog also.
The integration is very easy there is a link called add to blogger whenever you choose a widget.
