Lawrence Calvin Foster III, commonly known as Rusty Foster, is the founder of Kuro5hin, and the creator of Scoop, a collaborative media application used by several websites. He is widely known in the weblog community for running a donation drive which netted over US$39,500. However, the Collaborative Media Foundation that Foster promised to set up with the money never materialized, and Kuro5hin.org is hosted for free by sponsors, it was not known what he did with the money. He later admitted using the funds to pay rent and buy groceries.
He is a left-wing activist, and has fought for the independence of Peaks Island, Maine (where he lives) from the City of Portland. His wife Christina served as the Recording Secretary of the Island Independence Committee.
Foster later entered the political arena, partnering up with left-wing weblog moguls such as Markos Moulitsas Zúniga of Daily Kos. Foster served as the CTO of Armstrong Zuniga, a consulting firm formed by Zúniga and Jerome Armstrong in 2004, but the firm has since been dissolved. Daily Kos operated on Foster's Scoop software until February 2011, as do many smaller sites.
