Yahoo has added open-source blog publishing software to its Web hosting.

The Net giant has struck a deal with WordPress and will add its software alongside proprietary alternative Moveable Type, which whom Yahoo struck a deal last week. The deal is intended to broaden the blogging software options accessible to individuals and companies that use Yahoo to host their websites, the company said.

Both blogging options will be a free option to all new and existing Yahoo Web hosting subscribers, whose most basic plan that costs $11.95 per month. "We’re committed to working with industry leaders to provide top-notch publishing platforms," said Guy Yalif, Yahoo's director of Web hosting products.

Installing and maintaining WordPress via the Yahoo service will require just a few clicks, and thus will be much simpler and quicker than if users do it manually, said Matt Mullenweg, WordPress' founding developer. Yahoo will automate tricky technical steps, such as setting up a database and configuration files, Mullenweg said.

"We're making it very easy for professional bloggers to use WordPress so that they can focus on their audience and message, instead of on the blogging software infrastructure," Yalif said.

Yahoo will automatically update WordPress whenever an upgrade is available, so users don't have to worry about keeping up with new versions, Yalif said.
