Republishing an Old Post?

Has anyone ever done this? I was trying to look up information about this and the advice seems rather confusing. Some people say just copy and paste the text into a new post – others say that’s a very bad thing to do because duplicate content is FROWNED upon. Other people say just change the date on the post – the opposition say it’ll break your permalinks, and it won’t be visible on Reader anyhow! One advice was to use the reblog button but wordpress.com support you should instead make your post a sticky!

What I’m trying to do is to take a post from the time in the very beginning when I existed in a vacuum without followers 🙂 and share it. For what it’s worth the sticky post advice didn’t seem good advice for what I’m trying to do…

Any advice? @neatusername perhaps? You seem to know about such things.

Thanks!
