TwitThis - send Twitter messages about your blog post or website

Have you ever wanted to get the twits straight from your web page or a blog? Something like the other tag or bookmarking services.

TwitThis is an easy way for people to send Twitter messages about your blog post or website. When visitors to your website click on the TwitThis button or link, it takes the URL of the webpage and creates a shorter URL using TinyURL. Then visitors can send this shortened URL and a description of the web page to all of their friends on Twitter.

Here is how you can add this. You can use an Image or a text to do it.
a. With Image

<!-- Begin TwitThis (http://twitthis.com/) -->
<script type="text/javascript" src="http://s3.chuug.com/chuug.twitthis.scripts/twitthis.js"></script>
<script type="text/javascript">
<!--
document.write('<a href="javascript:;" onclick="TwitThis.pop();"><img src="http://s3.chuug.com/chuug.twitthis.resources/twitthis_grey_72x22.gif" alt="TwitThis" style="border:none;" /></a>');
//-->

</script>
<!-- /End -->

b. With text as 'TwitThis!'

<!-- Begin TwitThis (http://twitthis.com/) -->
<script type="text/javascript" src="http://s3.chuug.com/chuug.twitthis.scripts/twitthis.js"></script>
<script type="text/javascript">
<!--
document.write('<a href="javascript:;" onclick="TwitThis.pop();">TwitThis</a>');

//-->
</script>
<!-- /End -->

Antonio Lupetti has another good example of having Image and 'Twit This!'
