So, here is the new method which will add exactly the same button, without adding any additional scripts to your blog.
In just two steps, you can have this button working on your blog:
STEP #1:
Log in to Blogger, go to Layout -> Edit HTML
And find (CTRL+F) this code in the template:
<div class='post-header-line-1'/>
STEP #2:
immediately below it, paste this code:
1: <!--ORKUT-SHARE-START-->2: <b:if cond='data:blog.pageType == "item"'>
3: <a expr:href='"http://promote.orkut.com/preview?nt=orkut.com&du="
4: + data:post.url + "&tt=" + data:post.title' target='_blank'>
5: <img src='http://code.google.com/apis/orkut/docs/images/share.gif'/></a></b:if>
6: <!--ORKUT-SHARE-END-Help-http://whatjainsays.blogspot.com-->You can use any image instead of the default Orkut-Share logo, like these:
DIRECT-LINK: http://i50.tinypic.com/14mz4ac.jpg
DIRECT-LINK: http://i47.tinypic.com/35bba5e.jpg
Save the widget.
To display this button, along with Twitter or Facebook buttons, use these tables:
Table to display ANY TWO BUTTONS at a time:
1: <table border="0">
2: <tr>
3: <td style="width:40%;">Paste Code For Orkut Here</td>
4: <td style="width:40%;">Paste Code For Twitter / Facebook Here</td>
5: </tr>
6: </table>
1: <table border="0">
2: <tr>
3: <td
4: style="width:25%;">Paste Code For Orkut Here</td>
5: <td
6: style="width:25%;">Paste Code For Twitter
7: Here</td>
8: <td style="width:25%;">Paste Code For Facebook
9: Here</td>
10: </tr>
11: </table>

Here comes the another feature of new orkut which I think would be very useful to Bloggers. Like Share on Twitter buttons which i explained last week, Orkut too released its API and now you can have share on orkut button on any blogging platform like WordPress and Blogger aka Blogspot Blogs.
Let’s get started with How to add Share on Orkut button in your blogpost, at the end of blog posts.
How to add Share on Orkut button on Blogger / Blogspot Blogs
Go to Edit HTML tab under Layout of Blogger — Expand Widget Templates
Press CTRL+F and find </head> Now, just above or before this paste the following code.
<!--orkut share starts here-->
<script src='http://www.google.com/jsapi' type='text/javascript'/>
<script type='text/javascript'>
google.load('orkut.share', '1');
google.setOnLoadCallback(function() {
var params = {};
params[google.orkut.share.Field.TITLE] = '<data:blog.pageName/>';
params[google.orkut.share.Field.DESTINATION_URL] = '<data:blog.url/>';
var connection = new google.orkut.share.Connection(params);
document.getElementById('orkut-share').onclick =
function(e) { connection.send('orkut.com', {}); };
}, true);
</script>
<!--orkut share end-->
Now find <div class=’post-footer-line post-footer-line-1′> and add this code immediately after it
<b:if cond='data:blog.pageType == "item"'>
<span id="orkut-share" style="cursor:pointer; border:1px solid black">
<img src="http://code.google.com/apis/orkut/docs/images/share.gif"/>
</span>
</b:if>

How to add Share on Orkut button on WordPress blog
Comparing to Blogger, its somewhat easier to add share on orkut button on self hosted WordPress Blogs.
There is a Share on Orkut WordPress plugin which makes it very easy to do it but why add a plugin for such a small thing and increase load on webpage when you can do it simply by adding a code.
1: <a href="http://promote.orkut.com/preview?nt=orkut.com&tt=<?php the_title(); ?>&du=<?php the_permalink() ?>">
2: <img src="http://code.google.com/apis/orkut/docs/images/share.gif"> </a>
Done!
