Hal Plotkin, a tech writer and community college board member from Palo Alto, has landed a job in the Obama administration as a senior policy adviser in the Department of Education. Plotkin has written for SFGate, Inc.com, Metro and helped create public radio’s “Marketplace” program. When Foothill-De Anza Community College Chancellor Martha Kanter was picked by Obama to be an undersecretary of administration, she tapped Plotkin — who sits on the college district’s board — to serve as a policy adviser. Plotkin talks about the move on his Web page.
