Former U.S. Senator Bill Bradley, currently a managing director of investment banking firm Allen & Company, has joined the board of directors of Gather.com, it was announced Wednesday.

Gather.com is a Web portal that seeks to establish a platform for a wide audience of individual Internet content creators.

Bradley's appointment followed a $6 million second round of financing, Gather said.

"By providing a platform for people to share diverse perspectives on a broad range of subjects, Gather.com taps into the essence of what makes this world so great," said the former Democratic New Jersey senator and presidential hopeful in a statement.

Gather seeks to organize content among its members, who are bonded through the portal's community, rather than having to blog away on their own, according to the firm. Gather plans to integrate community ratings with advertising and a rewards system to compensate contributors. Membership on Gather is free.

In taking the board position, Bradley joins Jim Manzi, former chief executive of Lotus before it was acquired by IBM.
