NServiceBus Publish() vs. Send() in website context

Question

I'm looking to gain a better understanding of why it is recommended to never Publish() messages from a website using NServiceBus (NServiceBus Documentation, scroll about two thirds of the way down).

Doesn't it make semantic sense to Publish() events, and to Send() commands? If so, I think it makes sense that a web application can both Publish() and Send() :-)

Also, given that using Publish() doesn't require the web application to know about the recipients of the messages (Send() requires the web application to have all recipient endpoints configured), it feels like Publish() is a better option for many scenarios so that you can 'arbitrarily' subscribe applications to message queues.

Does anyone have strong feelings about this, one way or another? I'd love to hear your thoughts and opinions.
