Blogger, Google’s 11-year-old blogging platform, will be kicking it into high gear in 2011 with a few improvements. Premiered this year at SXSW, Blogger will be launching a completely overhauled user interface, putting to rest an interface that has begun to show its age. Following on its heels will be new mobile themes, and a new content discovery engine, “that lets you uncover interesting and related content based on the topics of the blog you’re currently reading.” Google promises that there will be more to come, but they are not ready to reveal anything else at this time. 2011 is starting to sound like a big year for the blogging giant, and it will certainly be interesting to see what comes of it.
