Question for any LJ hackers or mathematicians out there

Well this is puzzling. I'm working on a quick dirty Perl hack for downloading my journal (comments and all). It goes like this:

#!/usr/bin/perl
use LWP::Simple;
for ($count=579; $count<600; $count++) {
$head="http://www.livejournal.com/talkread.bml?journal=solri&itemid=";
$url=$head . $count;
$content = get($url);
print "$content \n";
}

Of course the last bit will be changed to append to a file, rather than fill the terminal with HTML. The problem with this method is that most itemids aren't used (so you download zillions of error pages), and I can't see a pattern for the one's which are used. I mean, can anyone see anything meaningful in this sequence?

76946
77116
77555
77741

OK, the numbers get bigger, but that's not much help. Of course I could include a search string for "No such entry" and not print that to the file, but I'd still waste time downloading a few hundred error messages for each journal entry.

Uludağ'a boş verin

Şimdi öğrendim ... Yılbaşında Uludağ'da kalmak, $1,000 eder. Bir pide bir iki dolar. Oysa, Uludağ'a gitmek terine, bin kişinin karnını doydurabilirsin. Daha iyi bir fikir, değil mi?
