IMhaha is a multi-network Web based messenger that supports four of the top instant messaging services including MSN, Yahoo!, AIM and QQ (China’s leading IM with over 200 million active users).
Using a Web based messenger like IMhaha is useful at school or work where Windows Live Messenger might be blocked or you are not allowed to use instant messaging, as it allows you to sign in using just your Web browser.
The service has been around since early last year, so in some cases it may be blocked where instant messaging is not allowed.
TechAddress has an interview with IMhaha, revealing more about the Silicon Valley based startup such as what sets them apart from other similar services, and an explanation about the interesting name.
