This is what happens when you're on the frontpage Answered
Here are graphs of the stats of two of my instructables. They clearly shows that being on the frontpage or featured in the weekly newsletter really gives you a boost.
The Marble Clock (the graph with 0-5000 as the scale for pageviews) got in the frontpage as Popular in the afternoon the 14'th, you can clearly see the rate increase of pageviews.
The Spooky Led Lamp (the graph with 0-10000 as the scale for pagevews) made it to the Weekly Newsletter sent to the subscribers in the eventing the 14'th. As can be seen on the graph the numbers of pageviews increased really fast at the next few hours then went back to the normal pace again. In contrast to what happened with the Marble Clock this instructable also got a real boost in the ratings due to the newsletter.
Here's a link to the Instrugraph Instructable.
