For a couple of days now:
500 - Internal server error - Bitcoin Charts
If this keeps happening I'm going to be looking for a way to look at charts that's super easy like bitcoincharts was.
Yes...
I used that website, too... From my perspective, it was especially good for looking at historical data... so to be able to customize dates and then to look at the chart that would be generated from those inputted dates.
Of course, there were quite a few other options, as you mentioned.. and pretty straight-forward abilities to use the options.
