Every website or forum falls into a niche. Some are more popular/saturated than others. That being said, do you feel picking a popular niche for your website or forum, IE: Gaming, promotion., could lead you being lost in the crowd?
Personally, I feel like it all depends on the content you drive to your website or forum, offering up interesting takes on even the most popular discussions and making content people want to read with good SEO, any popular niched new forum could succeed in my opinion, you just need to put the proper work into it.
