I wonder if the demise of Digg three years ago and the (supposedly) inflow of new users have been problematic at the time.

There wasn't actually a very large jump in traffic when Digg v4 was launched. Most of those folks were already reddit users. Traffic bumped a little bit, but not all that much.

It's important to keep in mind that reddit was already doing twice as much traffic as Digg before they launched v4.

Thanks for your input, didn't know that.

I, for one, went from a /r/php lurker to real user at that time so I thought there was dozens of us, dozens !

Most likely as Reddit had continued downtime around that time with EC2/EBS scaling issues.
