The one thing Reddit is great for, and for which substitutes do not yet exist, is its crowdsourced information. Especially product reviews. And finding those from within Reddit is impossible because their search simply does not work.
Appending "Reddit" to a Google search remains the best first-past method for making certain kinds of decisions where you need concrete, good-quality answers. Even for that, it's a bit of a minefield. Especially post-mod-purge, a lot of the once-great enthusiast subs have gotten pretty blase. Still better than all those consumer advertorial "BEST OF 2024" lists that you find everywhere full of extremely mediocre and likely corrupt reviews, but nothing compared to the straightforward buying guides you used to find.
On top of that, the "new" sight is a million times less usable than old.reddit.com and search engines shoot you in through that terrifically terrible gateway to experience confusingly-organized and incomplete content. Orders of magnitude worse on mobile, too.
If Reddit is de-indexed, I'll simply never be there at this point. Though I admit, I'm already there extremely rarely.
