The crypto scene is the most "group think" thing I have ever encountered. Most of it stems from reddit, which is an easy-to-manipulate hive mind. There are even busineses that attempt to sway opinion using paid shills.
LOL, if you hang out here long enough, it will become abundantly clear that there is a multitude of alternative and conflicting opinions expressed here. I mean look at r0ach. A good portion of his posts are definitely not popular, yet a good portion of his posts remain. The moderation on Bitcointalk is actually quite light compared to reddit. Both the btc and Bitcoin thread there appear to be echo chambers.
