His point is that the starting point for a random hacker would be to scan a range of IP addresses. If your ports are all invisible, he doesn't know whether anyone is using that IP. If you have a closed but visible port, the hacker knows there is computer using that IP and depending on the visible port may even be able to determine what OS/firewall is on there. That's the theory anyway.
In practice, I wouldn't worry about it too much.

Good point. Does Norton qualify as a decent firewall? :p:

Mind you, many trojans gain access via popups...and I'm running Firefox, which of course tells popups to get stuffed unless you say otherwise. :p: I'm also running NoScript (thanks to Carol a.k.a. Bald Eagle of the Windows Annoyances forum for that one!), so malicious Java code can go play with itself, too. :D
