I could read that indeed (couldn't get RSS working anyway).

The e,ha,cement I was suggesting does not concern titles, but the way text 
inside an }}}
<eucode>...</eucode>
{{{
 is rendered. I assume the highlighting there 
is done using HTML tags, so there are tags there already. The point would be 
to turn text a coloring tag into the color parameter of a <a href=...> tag.
The transformation doesn't have to be after highlighting - that would
 probably create subtle bugs -, but in whatever renders the }}}
<eucode> tag.

Consider the following line, taken from your recent news.exu post, and
 reformatted for clarity:
<br><pre>
<font color="#FF00FF">
        printf
</font>
<font color="#330033">
(1,
</font>
<font color="#00A033">
"\n1. my task id is rubbish: %g\n"
</font>
</pre>
<br>
Since "printf" is recognised as an Euphoria keyword, it currently gets a
 formatting tag around it. What I was suggesting is not to add tags,
 but change the current one. The change would be:
<br><pre>
<a href="www.rapideuphoria.com/lib_p_r.htm#printf"> 
        printf
</a>
<font color="#330033">
(1,
</font>
<font color="#00A033">
"\n1. my task id is rubbish: %g\n"
</font>
</pre>
<br>
The other tags do not refer to keywords and do not need any change. The 
trick here is to replace coloring by a link.
Using CSS, you can further customise the appearance of the link, adding a
&lt;div style=...> marker around the link in replacement of the current
 &lt;font> one.

Did I miss anything?
