it's really one of the greatest spaces I've ever seen.
The content, the appearance... actually EVERY THING.
But I recognized some thing which I really disliked it, YOUR SPACE is showing nothing of who you are :)
I mean I think you should have written something, ANYthing ! about your personality, that's why they call it Space " to let every one know who you are and the other things (contents... etc) are one of the things to keep your visitors visit your space all the time :) (In my own opinion)
