I think the space could be used more effectively. I like everything that's present on the page at the moment, but it's a bit unbalanced. HOWEVER, white space is good. hubski's current design is minimal and shows a lot of respect for spacing etc. This is good. Profiles shouldn't be any different. But with that said, if there's a way to integrate a bit more balance without them seeming cluttered, that would be great.
White space allows for the brain to seperate content and navigate more easily
More effectively means what you place somewhere ahs what meaning? is it relevent does it do what it is supposed to do do you need 15 words to say one thing etc something Microsoft has only just in the past 5 years realised they need to work on and they still get it wrong
