Try Texty

Texty lets you edit content on a website through a simple content management syndication (SCMS.) Texts you create are portable, that is, they can be embedded through a widget.

If you have several blogs, for example, and you maintain a section on each blog on "About Me," you can centralize maintenance of the text in this section via Texty. Any updates you make by Texty automatically updates your multiple blogs.

It's simple and easy. Try it.
