If you want to see whats percolating in the high-traffic subreddits, use r/all. I find it's worthwhile to check it no more than once a week, but it's useful for checking the pulse.
I think people are committing the age old error of romanticizing the past
How do you feel about the quality of advice Reddit gives on subjects that you are an expert in?
Because I know how I feel and that makes Reddit the absolute last place I would go for advice on something I'm unfamiliar in. I can google something and skim the top results myself.
Reddit gave me the impression they are surplus genuine OEM keys. I paid AU$45 rather than AU$339. Mind you, if I change harddrive or motherboard I have to get another license, but I'd have to do that 7.5 times before I've spent $339.
Went ahead with the purchase, activated by phone no problems. All good. Thanks Reddit.
My other recent use was to get a feel for whether the diesel heaters for motorhomes being sold on eBay for ~AU$300 are any good, versus the name brand units at ~$AU2000. Yep, all good, went ahead with the purchase, no problems, all spare parts available. Thanks Reddit.
Seems to work as intended, for my use case anyway :D
To answer your question though, I actually don't know! I'm an expert in about four fields-- anatomy & pathophysiology, nutrition, metal fabrication and laser cutting / CAM of ferrous and non-ferrous metals, 2D CAD, but haven't really thought about looking at Reddit on those topics. Maybe I should, I might have something to contribute.
People keep saying Reddit is blah blah.
I usually only go to Reddit to find an answer / solution / review / commentary on something specific, and via internet search always land in some subreddit or another which seems like a fairly reasonable community.
