Dear VZW Community Team,
I find the 'Quick Reply' option immensely useful because it does avoid the slow reload of the entire page and opens up a quick textbox for me to type the response. However the confirmation message still says I need to reload the page to see the response in context.
It would be still a complete Web 2.0 AJAX experience if on submit in Quick Reply the response also appears in context without necessitating this reload. If that is the case you can do away with the confirmation message too because the user anyway sees his post right?
