I don't think I understand what you're saying. If the connection is encrypted using a passphrase, I don't see how anything is exposed. Can you explain more?
Secondly, if the SSID (wireless network name) is not known to begin with (by not broadcasting it), it makes things a little harder (but definitely not impossible) to break into.
Anyhow if you're happy broadcasting your SSID, that's cool and cheers to you. I'm not and shouldn't be forced to. It's a pretty basic feature of WiFi and should be supported by all wireless devices.
