Hi I am a newbie in drupal module developement, I have my website http://seydinet.com 
made with Managing News and now I just want create a module who if I run my cron post automaticly a tweet with a message telling for exemple "4news item added in seydinet.com"
So I create a module directory name seydi, I add both file seydi.info and seydi.module. I have no problem with editing seydi.info but the big deal is with seydi.module.
I start by implementing hook_cron() then I have to implement the code who gonna post the tweet and I dont know how to do that
Here is the begining of my code

<?php
/*
implementation de hook_cron
*/

function seydi_cron(){
//watchdog('seydi', 'my module just add something in cron', array(), WATCHDOG_DEBUG);
// db stuff
if (date('G', time()) == '19'){
//tweet
}
}

Thanks
