Pay to use twitter? FB? Hmmmmmmmmmmmmmm. Maybe I missed something as I never have heard of anyone paying to use basic features at those sites What your clients are talking about here is many of them pay here and expect communication just like any other service they pay for. Due to large amount of clients here can they expect that communication some times take few days? Sure. Being ignored though is not in their expectations from the average site user of any service they pay for. I do believe that is what they are trying to get across.
