Really appreciate this lengthy and thoughtful response!
You made numerous excellent points, but there are a few that really stand out.

First, obviously we agree that Deep Dives is a tool to combat the never ending streams of propaganda we're targeted by and it's surely one of the reasons for creating the project in the first place.

Second, love that you pointed out that though the seasoned diggers may be well versed in the lies of authority, gov., financial institutions, intel agencies, media etc., it is critical that the average person becomes aware of false narratives, even just a glimpse of the truth. There is too much at stake to let these lies go unchecked and unchallenged.

Third,

publishing their findings are ordinary folks that have discovered truths that have disturbed them.

This is another great point and one of the reasons we would like to broaden Deep Dives to include more voices.

Fourth,

Perhaps creating best practices and how to's regarding use of the sources you mention, like Wikileaks, Cryptome, etc., would decrease the learning curve and error rate of non-professionals digging into those sources.

Another great suggestion...and one we will certainly consider. Much of this can come from the members of the community themselves as to how to conduct effective research and sourcing. In previous posts we have included tips here and there but complete posts on the topic might be highly beneficial.

Certainly much more to unpack here and to mull over.
Thank you my friend, outstanding input, if I do say so...
Cheers!
