(1) I really appreciate you, your faithfulness, and your thoughtfulness.  
(2) I thought your comments about Winner's research were very good and insightful. 
(3) The one thing that seemed to be one of her main points that I do not think is limited to the area this data looked at is that people/teens usually do not live our values if we are left to work them out individualistically, living what we believe to be best works far better when there are supported pathways, supported integrity, supported choices, supported openness, etc.  
(4) I think saving the blog and reading it to each of your daughters at the proper time (as best you can gage it) and then giving them time to read it alone and respond later to you is a great idea on your part.  
(5)  "halfwaytonormal" is my favorite of all site names I have seen so far. Wish I had thought of it first! (Ha!  Isn't that an example of our wonderful self-centeredness.)  It is great.
