In addition to several other big-name hires, AOL (AOL) said Monday that Twitter co-founder Biz Stone will join the company as its strategic advisor for social impact, a part of its combination with online newspaper Huffington Post.

The Internet entrepreneur will focus on cause-based initiatives, including the development of a platform to facilitate people doing service in their communities, as well as the creation of a video series spotlighting companies and executives at the forefront of philanthropy.

“Arianna and Tim share my vision for aligning corporate resources toward meaningful change,” Stone said in a statement. “Together we will rally companies to think about new ways of doing business, share best practices, and strive for positive impact at all levels - from global to local.”

Veteran journalist John Montorio will join the company as the Huffington Post’s culture and entertainment editor, while Howard Fineman, a long-time political correspondent, will serve as editorial director of the Huffington Post. Fineman has previously served as senior political editor of the online newspaper. 

AOL chief executive Tim Armstrong said the moves demonstrate the company's “eagerness to hit the ground running following the rapidly-executed merger.”

As part of its overhaul, AOL last week slashed 950 jobs, roughly 20% of its work force.
