Usability 
Nokia Conversations which calls itself, "The Official Nokia Blog" is one of the handset maker's primary ways of interacting with users. It's really more of a tech news site than a typical dry corporate blog. Conversations is about firmware updates, game and app reviews and recommendations and coverage of Nokia in the news. And in keeping with the blog's name it's a two way communication channel, reader comments are accepted and encouraged. Nokia doesn't appear to censor negative comments either as it's very easy to find them on the site.
Conversations is available on the mobile web too. For the mobile edition Nokia is using a custom WordPress template.
