I don't know if I qualify as an "older parent" because DD is just turning 11, but I don't use the board as often as I did when we were first finding out how far out of the box DD was/is. Part of it is because we have gotten over the initial "what are we going to do with her" sort of phase, but also because as she got older she started advocating for herself and figuring out ways to get what she needed in school and out.
I've recently started back to the board because DD6 is now starting through the cycle of starting school and trying to get her needs met.
Both are also more involved in activities now so there is less time for me to spend here.
I always love the BTDT perspective, and it keeps me coming back, as well as the hope that I can help out with what we've gone through so far for others just starting.
