Full disclosure: I was a contributor at Gawker in 2009.
How has Gawker’s major redesign altered their traffic? It all depends who you ask and what measurement service you decide to use. They all seem to paint a slightly different picture and everyone you speak to will give you a different explanation for why it is so. Gawker had been using the measurement service, Sitemeter, that they proudly displayed prior to the redesign, and still exists on Gawker’s UK site in the old reverse chronological format they tossed away.
