We can share our Post through Twitter!

Tweet

I never thought that we can share our writings at Twitter. I posted one topic about Nice Talk tutor just after this one and I saw the Twitter button below the date of my posting. I tried it and my post is posted right away at Twitter.Wow. I was looking for Facebook and Google+ button but I cannot find anything. Can we share our post with other social networks too? I think they are only allowing Twitter. Is there someone who had tried posting our discussion to other social networks? I guess now our discussion can circulate freely around internet because we can share it on Twitter.
