I have played around with twitter, FB, occasionally commented on blogs and on message boards. I first explored using message boards when I was buying a guitar amp and then later when I was playing fantasy baseball. I find that message boards (like this one...) offer the best balance of personality and checks and balances (i.e. Admins...) to offer good answers to questions.
Sometimes I find that Tu skews towards low-carb solutions to many food questions but, given the large number of participating members who have found success with that tactic, it seems reasonable while we wait for science to answer the question "how many carbs does a man need?" (cf. Tolstoy...hee hee...).
I also think that having moderated discussions where people taking aggressive stances sometimes leads to policing. The baseball group was opposed to swearing but, during say Yankees-Bosox games the "game threads" would always be full of "You suck, no you suck more, you suck so much that..." sort of antics which can be amusing if you're in the mood. We don't get that here as much but every now and then something breaks out. I think that it's very important T1 and T2 to stand up for each other and, much of the time, people here do that. There are plenty of folks who have meandered in with a T2 dx that evolves into a T1/LADA/MODY dx and other people (Richard157 and natalie_c come to mind...) have also suggested that after years, they are perceiving what they've called double diabetes with elements of both.
I agree with looking at "cause" as something I'm very skeptical about because, when it's all said and done, no one is 100% sure if everyone with various genetic markers develops whatever type or if (or maybe how?), as Marina suggests, we are created by the environment. Personally, I don't look at those questions too much and am more interested in tactical approaches that will lead to strategic success, like Dr. Steven Ponder, although, as a pediatric endo, I suppose he's skewed towards T1?
Brian, are "glucotypicals" PWD or PW/OD? To me the word sounds like "typical" bg or the standard model without T1 or T2 or another type.
