One of the excellent members of the Wired Science blog team, Damon Gambuto, will be blogging about Science Fiction books each Friday. He will have plenty to blog about, and this series could continue forever.
When I read his blog, it reminded me of that Environmental Blogging Day I participated in last October. Many bloggers who love science fiction and science could write about science fiction on Friday. This is an idea that could work, especially if we had a bit of organization behind it...a widget or a badge to a weblink that listed all science fiction friday bloggers who are members of the Wired Science group. This is only a kernel of an idea, but I think it would be really cool!
