Just noticed this stat on the bottom of a BBC article (highlighted in yellow).

And then I went back a bit later and found this message on the bottom of a different article . . .

And I then clicked on the link 'traffic to the site etc' and came to this . . .

I like the popularity-o-meter but was totally confused by first getting visitor stats and then a 'normal level' message.

Will the BBC be making its visitor numbers available in real time? I hope so – light, normal and heavy doesn't really tell you anything (feels like a rainfall measure).
