If one is a hipster who wants to watch Bulgarian Neo-noir movies or a perv who wants to build a hentai collection then yea, there's a niche audience that some private trackers still serve.
I still agree there are useful sites like Bibliotik and Audionews but for most users a single general/0day tracker is sufficient for most requirements, even that though is gradually being rendered useless by DDL sites like sc***g.
