focusing on money will lead to a degraded kind of community and the substance of the content is the key.
Anyone else's take on this would be really helpful.
The evidence is splattered all over here and of course cryptotalk.org. You'll get no shortage of people in with that approach, how could you not? But all they'll do is keep spurting shit all over each other without paying the slightest attention to what anyone else writes.
If you make money out of that and they make money out of that then so be it. Don't expect anyone else to join or anyone at all to stick around when the money runs out. And I'm doubtful any advertiser would consider spending money there when the entire demographic is nothing but broke spammers.
As for the original question, I hate Reddit but go there because it's much faster than here for news. Stuff attracts huge threads within minutes whereas here it may not be mentioned at all or take a week or two to pick up steam. Something that tapped into that would attract me.
