Since most you have been wondering about advantages of Stackoverflow site over Google Groups, here are the couple of pointers -
# As soon as you type in Title for question in Stack Exchange site, it
shows related question. This makes it easy to find if such question is
already asked. No such feature with Google Groups.
# Being able to tag your question in Stack Exchange site which is not
possible with Google Groups. This makes searching on such tagged
questions absolutely easy. No similar feature with Google groups.
# Formatting of question(bold, italic, hyperlink etc), distinguishing
code block from rest of the post to make it stand out are excellent
features of Stack Exchange site. Google groups just can not with stand
# You earn reputation for every answers which is marked as right, this
gives you more credibility on site. Again Google Groups lacks this.
# Being able to thumbs up or down a specific question or answer, and
in fact close it eventually if it is off topic for site. No similar
feature on Google Groups.
