Today's activity was suggested by both Sue Waters and Silvia Tolisano. Their idea is that we comment on a blog post in another language. For some of us, this may mean dusting off our foreign language skills from high school or college. If you're like me, you'll need something a little more heavy duty to figure this out. Sue suggests trying Google's Translator, which should allow you to both read a blog post as well as translate your comment into the proper language.
To find an appropriate blog, try translation a keyword into the language you want to search for--for example, if you want to find a Spanish-language blog that discusses education, search for the keyword "educacion" in Technorati or Google Blog Search. Then copy and paste the post text into Google Translator, which should give you a reasonable idea of what the post says. You can then write your response and translate it into the other language. You might want to mention that you're using Google Translator for this purpose because your comment won't be perfectly translated. If you blog about the experience, be sure to use the "comment08" tag.
