Hi,
I think you need to know the subject indepth..
Those best practice documents were available and handy when not much content available on sdn.
Now if you go each space--content--blog--documents--you can filter them as per your need..
In each and every topic you have handful of documents,blogs.discussions.
So my suggestion would be to prepare a list topic wise then make a start and move ahead.
Yes if you have any particular query then you may post we would be happy to address it no time as usual.
Regards,
AL
