bagged lettuce?

If anyone needs an interesting research project- studying the bagged lettuce phenomenon might be worthwhile. I say this because I've been checking out my Google Analytics. My blog's second most visited page (first is the front page) is my entry about "Lettuce in a Bag". Of 17 google searches that led people to my site in the past month, 11 of them had to do with lettuce. I wrote this post in August, about my evolving relationship with bagged lettuce. Since then 45 people have stopped in because they wanted to know about lettuce (out of 69 searches total). First of all, I had no idea there were so many people curious enough about bagged lettuce to make it to #15 on their google search. Second of all, how am I still #15 after 6 months?
