I spent 10 minutes today to look into Yahoo Pingbox. I found the option under the "Messenger" menu and I said to check it out.
Yahoo made a pretty nice job by developing this little nice gadget. Basically it can be added to any website/blog/forum as an online chat option.
Want to add it on your website? Simple as 1,2,3... Go to Yahoo Pingbox website and start the "Create a Pingbox" process; it will take you maximum 3 minutes to get the HTML code to be inserted in your blog. The nicest thing is that the installation instructions are made for most popular blogging platforms (like Blogger for instance).
The gadget can be seen in action on the right side of this blog :)
Can be used this tool as an alternative for chatting online with your customers? Certainly YES!
