User testing for semantic applicatons

I must say something
There are a lot of cool applications coming up, I try most of them , but they are new  
I am not sure what to expect exactly. What should it do? How do I know if there is an error, or if this is really the way
it should look? Little documentation, usability almost not taken into account etc.
Also I dont have all day, just a few minutes, a few clicks, then I lose interest, must move on

Now, the linked data below is quite straighforward intuitive interface (not bad in fact) although a few more explanations and how to's would be good. I also got an error when I tried it (different from the error below) not sure what to do next

All this to suggest  a forum is created to handle usability of semantic applications, where we 'users' can
report our experiences and get some help in running/understanding the stuffs. I have a lot of feedback and user tests already running on semantic applications, may be most productive if handled collectively and shared, rather than just sent to the developers who are likely not to understand my problem anyway (we seem to speak different languages)

thoughts? 
cheers

  Something funny about the XML:  Line 2: doctype broken.  Shoud not be a doctype.
