There are certain topics that have to be avoided. Ironically the attitude is very anti-startup and against newer, unproven technology.
I'd actually love to see a community where we could discuss startups and new tech. Subbreddits tend to swing too young - opinions are strong but unfounded, and there's a strong bias against the tried and true. Something like Indie Hackers attract the idealists who have big dreams but do not act on them.
