I am be stopping by for a week to observe and understand Betas. I am particularly interested in understanding Beta culture, and also, for myself, understanding LSIs somewhat and your experience with them. Hopefully the "Beta Field Guide" can be useful, and I will go through the "Your experience with ISTjs" thread.
Also, I would ask each Beta Quadra member here to explain their relationship with the other Quadras, particularly the Delta Quadra, as they are supposedly opposite from you. (edit - and talk about intra-beta interaction as well, if you are up for it).
Your insights and observations will be useful.
