Staring for slightly too long?

[sawyl]

Apparently signing off your emails with "thanks", as I'm prone to do at work when dealing with someone I don't know, isn't exactly approved of by everyone:

You can sign off with “thanks”, but that is more often than not just confusing if your email contains no hint of gratitude at all. An email which ends with thanks that isn’t thanking anyone for anything is just kind of weird — it’s the email sign-off equivalent of someone staring at you for slightly too long.

Most of the time, when I'm dealing with someone I know or posting something to a wider audience, I don't bother signing off: I just say what I'm going to say and, at work, tag on my sig, and thus mark myself as a product of the low bandwidth era. It's a bit blunt but I think we've established by this point that rather a lot of bark was left on during the polishing process...
