Eight excellent web chat services

Perhaps many people think that communicating on the web is unproductive. Of course, if we're running personal blogs or individual websites, we naturally have full freedom - I can choose to chat or not, and no one can interfere. But there's a question I've been pondering for a long time: why do so many spammy online chat service providers in China manage to survive? They offer paid services, which means they’re taking money from users. This isn't hard to understand; most commercial sites need tools that allow them to quickly establish contact with their visitors. Fearless has also tried many of these services, but they always fall short of expectations. So today, I'd like to recommend some excellent web-based chat service platforms to everyone.
