I have two accounts, my primary as well as a secondary, public address that simply forwards to my main. This has the added benefit that I can label any messages from the public secondary address, giving me a bit of information about how the person found my email address. The downside is that the unsubscribe feature in Gmail does not work for most mailing lists, even if you set up aliases correctly. If that address ever does get inundated with spam, I can simply terminate it.
