The changes are designed to make the site more readable and its content more accessible. The re-launch introduces new section pages for news, arts and entertainment and bloggers. The sports and real-estate sections continue to have their own pages.
The site has an improved presentation of the Town Square reader forum, which is intended to encourage greater community discussion on important local issues.
A new community calendar format makes event information easier to access.
"We've sought to organize the presentation of vast amounts of content in a way that is clean and simple," said Bill Johnson, publisher of the Palo Alto Weekly, which operates Palo Alto Online.
"Like anything different, it will take time to get familiar with the new layout," Johnson said. Additional tweaks and improvements will be made in the weeks ahead.

In addition to the new design, the website features a number of new blogs by residents, who will discuss local politics, parenthood and other topics. They join staff blogs on food, arts and the community. More blogs will be added in the future.
