My problem with larger communities on Reddit is that prevailing opinions seem to emerge, and anything that questions or disagrees with them gets downvoted to hell. On the personal finance subreddits these include ideas like "You should always have 18 months of expenses saved" and "Any more than $10,000 for your wedding is a reckless and gross waste of money" and "Look how smart I am for having a mega-backdoor roth ira instead of a regular 401k like all the idiot sheeple."
I still think having a relationship with a financial advisor you trust is better than taking advice from strangers on the internet.
