Flock is cool, it could aggregate all the blogging space into one single area where you can put in tags, links, images so on and forth. And more over, it supports the registration of wordpress!
One major reason I love flock is because of the photo uploading utility and the clip board feature. With these two little tools, I am able to grab any information from any website. Putting them up onto a new blog post is just like breeze of wind – Simple and Elegant!
