My suggestion, since the non-pro version is limited and I quite like the MS translator for scientific texts:
Copy the complete blog including the interesting comments into MS Word.
Then click translate document.
If one language is English, the result is usually quite good and it only takes a minute. Also, if I'm really into the subject, I can make Comments, highlight parts, and save the whole thing on the HDD for future reference.
