It has indeed turned out that SFC is better as it seemed that day. Maybe Facebook needed their time to update all of their resources, furthermore I’ve observed even more Problems on the FB website at the same time.
Another really funny tool is Live!Zilla. It is sort of chat system for website operators. Apart from the PHP/mySQL based server component, a local client has to be installed on the operators PC. Unfortunately there is only a Windows implementation available. Macs and Linux are not covered.
Having this installed as a website owner, your site visitors can see whether you’re online or not, and if so, initiate a chat conversation. The other direction is possible as well. In the aforementioned Windows Client, you get a list of current visitors of your web site, and you get detailed information which pages they request, and you can actively invite them to chat with you. I’ve seen some corporations do that already. Don’t remember, was it Microsoft? Or Dell? Never mind, that scale at least.
I’d not be surprised, if there are people who have privacy concerns here.
