The blog, which will run in tandem with his web blog on the Kremlin site, is in the form of a social networking community with embedded videos where users can leave comments.
The LiveJournal social networking site is Russia's most popular blogging site with 19.2 million accounts worldwide and 2.8 million Russian-language subscribers.
In the new video, Medvedev said subscribers will be able to leave comments on remarks made by other users. "So if you want to respond to a blog visitor, and say what you want directly, if earlier it was rather complicated, now you have this opportunity. Use it!" he said.
According to latest data, the number of comments left on the 5-minute-long video post, located on the website http://community.livejournal.com/blog_medvedev/, is over 900.
Subscribers to the http://blog.kremlin.ru website, whose number has exceeded 16,000 with over 4,000 comments left since January, along with registered LJ users can participate in the discussions. Overall, 12,600 comments have been published on the site.
Today's post, which is located on both the LJ and Kremlin websites, is Medvedev's ninth in the last 6 months, when the head of state first started his Internet blog.
Respected business daily Vedomosti quoted a presidential administration official on Tuesday as saying the new blog would be moderated by the same team of IT experts as the current Kremlin website.
Medvedev has said he uses the Internet daily and believes it to be the best possible platform for public debate.
Medvedev urged officials to go online. "Many state bodies have developed rather good sites, there are successful examples of the implementation of electronic government, for example in Tatarstan," he said.
"And many managers were unable to deny themselves the pleasure and followed my example," the Russian leader said.
Recalling that information on the incomes of Russia's top ranking officials was recently published on the Internet, he said: "This is extremely important, however, this should not be a one off or an individual example, like now, but everyday work," he said.
Medvedev said this was the reason why he had established a presidential council on developing an information society.
He said another key task was to give everyone equal access to the Internet.
The president said he hoped the financial crisis would become a launch pad for new Internet developments that would not only benefit users but the Russian economy as well, and said the Internet could help create additional jobs.
