Is there a way to identify whether users are online or not? Something like online offline status symbols used in a chat application for every user.
Is this materially different to the "Seen:" field on the profile?
With no chat feature, online/offline status is useless?
It would be a nice feature with the option to turn it on or off, similar to turning on or off facebook chat. For various reasons I prefer my online status not to be visible.
SO.com is not a social networking site. There is no reason this feature would be beneficial on a programming Q&A site.
I think this is an interesting idea, but would be concerned about the overall number of users on the site at any given time cluttering it up. Maybe a count would be sufficient with the ability to drill into that number to see the user names?
This could also tie in well with the idea of a friends list where an icon could be added next to their user name if online or something along those lines (think Office Communicator type of thing)...
This is a nice idea. But do we want to see Stack Overflow act like a chatting site?
