Like if someone is going to do a reboot for testing could there be some way that they could set something so that if someone hovers over their name in a comment or answer/question that it could display their status? Someone could set status like "at work, can not respond at all", or "back in 3 minutes after a reboot", or even some "on vacation" thing to just show when they may be back. Not an enforced thing just an option.
Personally, I would hate to see this feature implemented. I can see no good coming of it except that I would now be expected to respond promptly to comments or chat messages because some indicator decided I am "here".
First of all, it's nobody's business but my own what I happen to be doing. This is not a social networking site and SE have, in general, resisted any suggestion that it become one. Many of us visit the site while working, for example, so I may be here because I'm looking something up but have no time to answer anything.
That said, there are actually two ways of checking when a user was last seen:
- There is a last seen entry in a user's profile:
- For those of us who ware active on the various chat rooms of the SE network, you can click on our chat avatars in one of the chat rooms and get even more detailed info:
So, you already have two easy ways of getting an idea whether or not a use is currently online. Adding more would be both too invasive (IMO) and add unnecessary clutter to the site and the SE engine.
