GMail现在支持在blog中添加gtalk(在线临时对话模式)在线图标,就像QQ的在线临时对话模式一样,也可以吧Gtalk的在线模式添加到blog中啦!官方是这样说的，偶的e文不怎么好，就把原文弄过来啦
If you have your own webpage or blog, you can also add a button to your site so your visitors can pop out the Google Talk Gadget when they visit your page. If you want them to chat with you, just list your username next to the button and ask visitors to sign in and add you as a contact. To add the button to your page, just copy this script into your site's HTML:

只要添加下边的代码到（比如csdn的blog，就是添到公告那里边就可以啦）网页代码中：

<script src='http://talkgadget.google.com/talkgadget/button' '你的gmail帐号，要带域名的啊，比如：[email protected]'></script>
