Obviously preaching to the choir here but:
Yeah, reddit feels very anonymous, so you can have a good exchange but you'll probably never talk with that poster again except on a small subreddit. Voting system also makes conversations disjointed, and subreddits create echo chambers
Bogleheads is nice but is strictly dollars and cents and there's only so many times you can talk about whether small cap value is worth it before your eyes glaze over. I like the implicitly broader scope of this forum (basically, financial freedom AND self actualization). Bogleheads is also filled with a ton of rich people that have a heart attack about the idea on retiring on less than $4 million or a 2.5 SWR.
Jacob's ERE forums are way too hardcore for me, so I wouldn't fit in.
I wouldn't mind if we just broadly changed this forum to add in more non-financial or tangentially financial things (a cooking subforum, a meditation / exercise subforum) but it's pretty great as is.
