sometimes the counters are erratic and show a question mark instead of a number. also- why does facebook and the add this button not show the 0 - whereas Twitter does.

The counter shows a question mark when it times out when requesting the count from our data center. We had some issues last week with this which should be resolved.
The Tweet button is written by Twitter and they've chosen to show the 0 when there are no shares, whereas Facebook and AddThis have decided not to. This design decision is out of our hands.
