SB Nation (Sports Blog Nation) presents a fan-centric, highly verticalized (i.e., local) view of sports from dozens of bloggers. The site has completed a new $10.5 million “C” round of funding, pushing it past the $23.5 million mark.

The new round is led by Khosla Ventures, and includes Accel Partners and Comcast Interactive Capital, which had also invested in earlier rounds. SB Nation has also received funding from Allen & Co. and angel investors such as former AOL executive Ted Leonsis.

The site, which launched in 2003 and now has 290 topical sites and 21 regional sites, is run by former AOL exec Jim Bankoff. AllThingsD reports that the new funds will be used to boost SBNation’s technology platform, its bloggers, mobile, local, advertising sales and a few relevant acquisitions.

Bankoff will be interviewed on a one-to-one basis at the upcoming ILM:10 show in Santa Clara. Investor Michael Yang from Comcast Interactive Capital is also appearing at the event.
