You may the following, but pagelist formatting is a tricky beast!

[[#blog]]
[[{=$FullName}|+]]

(:include {=$FullName}##readmore:)
(:if eq 1 {{=$FullName}$ReadMore}:)[[{=$FullName}|read more]](:if:)

[[#blogend]]

you need the conditional extension installed to do the eq comparison.
http://www.pmwiki.org/wiki/Cookbook/ConditionalExtensions

and define in your blog script a page variable:

# add page variable {$ReadMore},
$FmtPV['$ReadMore'] = 'StringCount($pn,"[[#readmore]]")';

now I was lazy and used the StringCount function included
in commentboxplus, maybe ther eis a better way with  abetter function.

function StringCount($pagename,$find) {
   $page = ReadPage($pagename, READPAGE_CURRENT);
   $n = substr_count($page['text'], $find);
   if ($n==0) return '';  #suppressing 0
   return $n;
}

then in the page I used as anchor:

[[#readmore]]%comment%{$ReadMore}%%

So it sets the anchor, plus a page variable, hidden as a comment.
The page variable is simply 1, and the condition in the fmt template
checks this.
The pagevariable could return not 1, but the anchor itself, but I
could not get the conditional to check against the anchor string.

You can check page variables with conditionals in the the pagelist fmt template,
but you can't check existence of strings in the text directly.

Hope this helps, and good luck!
(I felt it was needed to twist the conditional inside pagelist)
