Is it okay to recommend using meta.stackoverflow.com as a support channel for stackapp I've written.  For example, say I had been the person who wrote [StackPrinter](http://stackprinter.appspot.com/), on the bottom of the home page could I have something like:

> If you have any questions about StackPrinter, please post them on [meta.stackoverflow.com](http://meta.stackoverflow.com/) **with the tag "stackprinter"** for the quickest response. Otherwise you can <a href="http://[email protected]">email me</a>

Would this be considered acceptable, or an abuse? Perhaps we need a support.stackapps.com stack-exchange site?
