Well, its finally here, for me at least.
Facebook's long awaited chat program was ready and waiting this morning when I loaded up my browser. I haven't used it yet so can't comment on its stability although according to the odd twitter post it has been turned on for everyone today so the next few days will be the real test of its stability.
Facebook chat has been down for me most of today, it was up for a few hours this morning but I am now stuck with this "Could not connect to Facebook Chat at this time" message and exclamation mark. Perhaps the introduction of FB Chat to the world was to much for there system!
