"Open" to me leads me to think it is open source, but it isn't. I suppose common folk may not have that presumption. But I don't even think "Open" is descriptive to what your product does (other than maybe how it is quick to open). Loop is fine, as it express to me how you can be "in the loop". If you are getting rid of the Z or thinking of other names, I suggest using parts of another commentor's suggested tagline: "chat is your to-do list, and your to-list is your chat" for the name: e.g. "ChatToDo", "TagToDo", "LoopToDo", "TagChatDo", or even simply "InTheLoop" is better. Something along those lines that is more direct, specific, & descriptive than OpenLoopz, so that an uninitiated potential consumer has a bit of an idea about what it is your app does before even considering to click your link. (Regarding the www., I was another of those who just visited the naked url, and I immediately thought negative thoughts like, it's down, and almost didn't try again. You should atleast redirect the naked url to a valid url or landing page.)
