HP have just realeased a demo of there blogging app, blojsomIT!. At the moment it does a small amount of things but the next step SemBlogIT! looks to be really powerful and clever app which could come in useful later.
I have set it up for testing here. Obviously you need a user name and password to use it unfortually. But you can try out HP's own here.
I hope to add some serious feedback once I try it out over time.
