I recently deployed a Gtalk badge and got rid of the buggy plugoobuddy chat window. I am happy to say that, this badge is keeping my status as accurate as it can get. For the first time I was chatting with more than one visitor at the same time. I have no idea whats the problem with plugoo but never use to keep my status accurate.
The only problem with Gtalk badge is it doesnt allow chatting right from the page, but instead you need to click on the badge for a popup chat window. This is ok, but I would like to see a Gtalk badge written in iframe so that my visitors can chat without a popup window.
Anyways, I decided to move to Gtalk badge because I wanted to be able to chat with my website visitors right from Gtalk (thats one and only thing I use) .
