DP Alexa ranking graph

Why is there such a big jump in April? Will digg traffic cause the spikes?

 

I was wondering the same but Digg traffic wouldn't come back to sustain the increase. Could be as simple as a hand full of regular members now using the Alexa toolbar..

 

I think it is a change in way Alexa ranks sites, check out sitepoint or some other sites, many others also have a similar jump around that time.

 

You are right. I guess there was an Alexa TR update.

 

Oh yeah, I remember reading that now........

 

OT, but how come this links does not open in a new window?
