Are there any community-driven media sites that focus on commentary and discussion around industry trends?

Yes — there are several community-driven media sites that focus on commentary, analysis, and discussion around industry trends. A few notable ones:

• TechCrunch — Strong on startup and tech industry news, with comments and lots of industry discussion.
• Hacker News — Community-driven discussion around tech, startups, and broader industry trends; especially good for commentary and debate.
• Product Hunt — More product-centric, but the community often discusses market trends, launches, and industry shifts.
• Indie Hackers — Focused on founders and builders, with lots of discussion about business and product trends.
• GrowthHackers — Community around marketing, growth, and business strategy trends.
• Reddit communities — Depending on the industry, subreddits like r/technology, r/startups, r/marketing, or niche industry subs can be very active for trend commentary.
• The Dots / relevant niche forums — For creative and media industries, community discussion can be quite active.

If you want, I can also give you:

1. the best sites by industry (tech, marketing, finance, gaming, etc.), or
2. sites that are more editorial + community, rather than pure forums.
