Havent been active on the forums for a while, but back when I started really getting into peppers during my second grow season in 2014, this was the place I turned to in order to get my information. This, old youtube pod reviews (Nigels channel being one), and Khang Starrs youtube channel for grow advice.
That said, for learning about new varieties I just check out whatever looks good on the various trusted seed vendors I use, and for growing, I rely on my own knowledge after 8 seasons.
TLDR: reading this forums posts, youtube pod reviews circa early-mid 2010s, Khang Starr, trusted seed vendors, and many years of experience growing (best teacher)
