The Huffington Post is expanding once again, this time launching four new verticals: HuffPost/50, for the 50-and-over crowd; HuffPost Gay Voices, for happy content only (we think); HuffPost Weddings, for everything one needs to get married; and HuffPost High School, for all the Justin Bieber pics teenagers can handle.

If it seems like HuffPost launches a new site every day, that’s because it practically does. There have been 21 new sites launched since AOL and The Huffington Post merged in March. The growth isn’t even hurting the brand. Check out these stats: In August, HuffPost recorded 37 million unique visitors and passed one billion total page views — both for the first time. Oh, and people still love to talk on the site. There were over five million comments in August as well.

With traffic increasing, it’s no wonder the site launches verticals as often as Nicki Minaj gets a new weave. We’re sure there will be plenty more to come.
