Two days ago we had the longest "hang-time" on average per visit across 24hrs - longer than we had ever before. 13mins and 40 seconds per visitor. This means that ON AVERAGE people who came to the site stayed on for 13 mins and 40 seconds. If you want to count out 13mins and 40 seconds in a "one onethousand" count you will certainly get fatigued.
Wow, it is humbling to see the grass-roots influence on the site take hold.
