Which markup did you use? <div>...</div> around each tidbit, or
<br> between them, or something else? If you use <div> or <br>,
then there will be line breaks in visual presentation, of course
(except that I recently heard that an old version of Lynx failed
to do that for <div>!). It is debatable how line breaks indicated
in markup should be handled in non-visual presentation and whether
<div> should be handled differently from <br>. I'd say that
a) user agents should assume that such line breaks may be essential,
and should make short pauses accordingly; for example, they might
even correspond to the verse structure of a poem!
b) authors should avoid assuming that user agents do the above;
authors should try to find better, more structural approaches.

So you probably used <br> or <div>? From my experience with Home Page
Reader, that program, which has many excellent features in other respects,
often runs things together - maybe even if you use <ul> and <li> without
punctuation at the end of each item? Let's hope it gets improved.

But wouldn't <p> markup be more suitable for your purposes? The tidbits are
small paragraphs, aren't they? Using <p> would make HPR read the text well,
and it would not be just a workaround but a genuine solution. Moreover, HPR
lets (if I remember correctly) the user to skip the rest of a paragraph
with some simple keyboard command, and such "skippability" is very useful
and something that good user agents can be expected to support generally.
It is less obvious that a user agent should support skipping to the next
<br> or to the end of the current <div>.

Naturally, you could then use some CSS to style the paragraphs in visual
presentation as desired.

An interesting idea! It is more common (though not very common) to use
unordered list (<ul>) and turn off the visual display of bullets. Using
<ol> is probably better when HPR is used: it reads <ol> much more clearly
as a list than <ul>.

Which is actually part of the solution! Well, workaround. If you had used
<ul>, it might have read the items without noticeable pauses between them,
except as caused by punctuation in the text. (Disclaimer: HPR may have
changed since I last used it.) Thus, reading the numbers compensates for
this deficiency.

But the problem is avoided if <p> is used.
