I'd use it either in a validation or a callback to the model.

The truncate result is pool mostly time, so i think a more meaningful is useful

 You might checkout truncate_html and consider combining your functionality into there as options.

So, this would be something you'd use in a view? If so, it should go in
a helper.

[soffolk]

more than that, you can use it to produce your summary and save it into database.

I think it's a universal function, and we need not to limit it. just expand String

If you want to, go ahead. Put it in a module, then send :include to
String with your module name.

If you really did not want suggestions, why did you ask for them? If you
already have an answer you are settled on, why open things up? Just do
it, see what you get.
