I suppose you can do a JSON backwards compatibility, anyone have a ref to that?

Here is tweets_cron.php (also include the getTweets() function from the blog post):

$tweets = getTweets('saturnboy');
if ($tweets !== false) {
    file_put_contents('tweets_saturnboy.txt', $tweets);
}

Here is a snippet from my blog sidebar (not really, but stay with me):

$tweets = file_get_contents('tweets_saturnboy.txt');
print $tweets;

Done. Just put tweets_cron.php in the crontab hourly or faster. Of course, if you need multiple users, you can use an array of usernames and loop.

Thanks,
