I can re-tweet on Twitter. I heard Facebook has similar features. How can I do this ?
It isn't quite the same as re-tweeting. There are 2 related options shown underneath posts:
Like: This will add a comment to your news feed saying
"<you> likes <title>". It is only a link to the original post - it doesn't add the actual content to your profile/feed.
Share: It doesn't work for a regular status posting, only if it is a link someone else has posted. Underneath the post, with
Like there will be a
Share link. This will have it show as a post from you with
"via <name>" to indicate the original post came from someone else.
