Your post happens to demonstrate one formatting tip that seems to make a difference on my linux-based Netscape 4.78 browser:

Whenever I view a post with a <UL> or <OL> construct, and the close tag for the construct is followed immediately by text (without a <P> tag in between), the last list element and the first line of text overlap on the same line of the display, and are not readable -- I need to view the page source to see what was actually written. (Oddly when I reply to such a node, the same markup displays correctly, no problem.)

In any case, I have gotten into the habit, when using the list elements in my own posts, of always putting a <P> right after the end of each list -- this always assures a good display.
