InboxQ's core functionality is very nice, and I've been using it lately to help promote one of my products.<p>I haven't been able to figure out why it is delivered as a browser extension, though. It doesn't seem to add any value, and in fact makes it more difficult to use than if it were just a standard web app. For example, if I have InboxQ popped open in Chrome and then I switch to another application to do some research or copy a link, then when I switch back to Chrome, InboxQ is closed.
