Barack Obama will unveil several new technology policy initiatives today during a visit to Silicon Valley, including a proposal for a national technology czar called a "chief technology officer," VentureBeat has learned.

The Democratic presidential candidate comes to California seeking to bolster his standings here, where he currently trails front-runner Hillary Clinton in most opinion polls.

Obama's tech agenda, including the CTO proposal, should play well with the employees at Google, the Mountain View search engine, where Obama will visit this afternoon, among other stops.

The CTO's mandate under the plan is significantly different from the cybersecurity czar position created by the Bush administration. The CTO's main responsibility would be to ensure the government holds open meetings and records live Webcasts of those meetings, and that blogging software, wikis (Web site pages where multiple people can edit a document at the same time) and open comments be used to communicate policies with Americans.
