Curation is the lifeblood of Reddit and some subs are insane in their quality and dedication. Maybe there are some in those subs who would contribute longer form content to Lifhacker in the future but the differing business models makes this unlikely in the near term IMHO
On the other hand, you can end up in situations where moderators are the only source of truth. The california subreddit is an example of this. 432k subscribers, yet the vast majority of posts come from a single moderator. At least they are posting mainstream news articles and not fringe content, but this seems to depend on one person with no check or balance.
Notably, they both coexisted back in the day, too.
If they seek to be an honest source of information they ought to stand out in modern net sources. We all know the hell of searching for info on google nowadays.
they definitely didn't coexist 15-20 years ago, which was maybe the reason I read LH back in the days, Reddit was founded less than 18 years ago and even in those first few years had hardly any users, started using it maybe 11 years ago and even then it was quite empty
stopped reading LH already before starting with Reddit
