@zasad@ start some interview with bitcointalk members  you can check some of them here ---> https://bitcointalk.org/index.php?topic=5262967.0
I don't think you will get many good interviews here because many members care about their privacy.
Some of the old members are still active and maybe they are the only ones you will benefit from a lot but they are few.
In general, you will not lose anything from trying, as the forum witnessed the beginning of Bitcoin.
