Let's look at the particular context the OP had. Stuff like:
<h2>What products/services are suited for e-commerce?</h2>
Certain products/services appear more suitable...
<br/>
<br/>
The ideal products/services...
<br/>
<br/>
Products unsuitable for e-commerce...
<h2>How can I benefit from e-commerce?</h2>
These things are *clearly* paragraphs yet the author did not mark them up as
paragraphs but used <br><br> under the mistaken assumption that this would
produce a blank line visually. It might in some browsers but it is not
specified to do so. The author is probably totally unaware that this might
*not* produce a blank aurally.

Exactly. A truly well designed website. A poorly designed one (like this)
could well drive people (the visually impaired) away.
What I'm really saying is that if it's a paragraph put it in a <p>
tag. That's the underlying message.
Exactly, except that it is a paragraph element. The paragraph element
includes the opening <p> tag, the content, and the closing </p> tag. *That*
is what an aural browser is looking for to create pauses. Pauses between
paragraph elements. Not pauses *at* <p> tags or <br> tags. The author of the
subject page seem to be under the mistaken impression that <br> and
possibly <p> are "commands", like \r\n in a word processor.
