Comparrison chart might be a good idea but that may lead some to believe its as "do it for you" as ADDT where it is not.
As for "how to" videos/guides to some extent that could be very good but as there isn't a single way to accomplish a task. There are any number of ways to accomplish a set task so layout out a single way may lead to more problems as many are still expecting the hold your hands approach where these are developer tools.
Its a bit like buying lots of mechanics tools and expecting to be a nechanic.. it doesn't happen.
A lot of the problems on here with DA could be put down to user error or misunderstnanding although not always the case.
With a bit of effort these tools are excellent.
