People were made about the VGbootcamp thing because of the #FreeGimR campaign and the significant drop in quality and promotion. Also, the proceeding issue with the vods definitely didn't help the situation. Not to mention this comparison is very shaky. From what I can tell, PM underground isn't trying to replace Smashboards, it is trying to occupy a different niche. The boards will always be the best place for discussion. Reddit has a wider reach, better suited for a wider range of topics (like tournaments, or gfycats), etc. This website doesn't have a forum, which is already different from the other 2. It also links to both Smashboards and the subreddit, so it doesn't seem like they are trying to replace them. Pm underground seems more geared towards things like articles, guides (and before you point to smashboards, any guide will probably end up on both if the creator is ok with it), a place to host/promote salt mines, etc.
