Some Mac reading

Paolo Valdemarin, while bemoaning modem connections like mine, writes:

There are about 10 tcp connections open at all time, web, mail, a few IM clients, Radio doing its things. But also things like the help system of MacOS X relies on a connection and doesn't work if it cannot ask something to a central server. [Emphasis mine.]

Guh, really? Why is that? Paolo's other Mac-related writing today is also nice reading. (And not only because he was nice enough to reciprocate my link to RssDistiller on Stapler's page.)
