Why is there so little actual discussion here? (2 Viewers)

I didn't imply that, I simply wondered aloud why this section of BF isn't busier considering the amount of lookers there are.
...

A few days ago I selected a small sample of n=40 different threads that appeared in sequence, and recorded the number of posts and views. Ten turned out to be binocular threads, and 30 were birding threads. In other words, one in four were about binoculars.

I then compared the views-per-post ratios of the two groups using a t-statistic to test for mean differences, and an F-statistic to compare variances. Although this is a very small sample, and an inefficient test due to unequal group sizes, there was no strong evidence that binocular threads have any different number of views per post than others. Neither the means nor variances were significantly different. Overall, there are somewhere between 44 and 56 views per post.

Several more refined analyses could be done with a much larger sample, but with no easy way to download the numbers and eliminate identical threads, it would take a great deal of hand labor.

So this is just a small push-back to question the basic premise ... :eat:

Nice synopsis Brock. I think you did a ver nice job of summarizing one of the general trends of behavior here. Now I think I need to head over to the Swaro booth to check out the CL pockets.

On another note my timing in reading your comments was perfect. As soon as I finished reading your post I looked to my left and there was Stephen. I read him your quote and he laughed at the fact that his quote is in your signature line. A very humble man.

Frank,

I wish I had seen your post earlier, had to work this weekend and went offline to keep myself from being distracted (I'm online so much that Norton 360 panicked and thought something was wrong with my computer and gave me an ALERT because it couldn't check online for updates). I would have asked you to give a "shout out" to my biding optics mentor and to tell him that I carry Zip Locks whenrever I use my 8x32 SEs on an "iffy" weather day.

The only thing that beats the SE on an overcast days is the Vixen 7x50 Foresta. Did the sun come out? Nope, that's just those large 50mm triplet objectives shining.
