Plugin for sharing blog post from front page

Hi folks,

I’m searching for a plugin or script that allows visitors to share posts from the blog frontpage – like on http://techcrunch.com – I need it to be possible to share each post and not just the whole site.

My site is http: http://www.trendsonline.co

Thanks!
Lasse
