If it happens to be down you could always go to bitcix.com.
I'd not seen that one. The blog and news stuff takes significant real-estate from the charts, but in actual fact they are probably more useful than the extra chart pixels in a lot of cases.
No charting service should be without btcchina exchange these days. It is probably the dominant force in Bitcoin markets at this time. Overlaying btcchina and one of the big Western exchanges could produce very useful visualized data I think.
Nice to have options. I inevitably fall back to bitcoinity because that is what I started with years ago. The user experiance in terms of response of both bitcoinity and clarkmoody are really impressive and fun to me. It is also fun to try to guess how they are working under the surface. They and bitcoincharts and some interesting anomalies which provide clues here.
