Meebo just launched a new service called MeeboMe which lets webmasters put a chat widget on their Website. Users will then be able to see when the publisher is online and chat with them directly.
This only allows one-on-one conversations at this point but could be expanded to group chats in the future.
A unique that about MeeboMe is that the visitor doesn’t have to be the one that initiates the conversation. A publisher can also ping a visitor and start chatting. Surely, it will be weird for the visitor!
Using MeeboMe not only means you save money on bandwidth but they take care of all the development costs. I am sure they will continue to add new features to it that will make it even better. So bloggers go and try your hands on it.
