Can someone please explain Livejournal Syndication (which is something that has apparently happened to this site).

Why is it that Livejournal users can't just visit the original site, instead of having a copy in their own little island of the internet?

More importantly, is this something I should be happy with, or should I be upset?

How can I easily read comments that people leave on this syndication?

Seriously - I spend nearly no time in 'Livejournal-space' and have no understanding of the why and wherefores of it.
