The fact that there are almost 800 posts on children going off the derech shows that Yeshivas, synagogues and Parents need to deal with this problem in a serious manner.
No, it only shows that members on this board enjoy discussing it — nothing more, nothing less.
PRofessional people skilled in dealing with this problem in conjunction with Yeshivas parents and synagogues should provide guidance on this and hopefully it will prevent many from going OTD.
That may or may not be true, but it does not follow from your premise (i.e. that because there are 800+ posts in one thread on the CR that this is what should/must happen).
