Wisdom of the crowd is a powerful thing and quite accurate when estimating the weight of Uluru or that of the famous ox.
With regards to GCar and Chris....I mean Thesi...what does the wisdom of the crowd tell us? GCar and Thesi have approximately the same number of total posts but one has received (statistically significant) only half the number of light bulbs.
When in doubt, ask the crowd.
Easy, hey!
