It did cross my mind that it might be coming in our direction as we cannot see a tail, but having found a picture on the web taken by the professionals (I guess, as I can't remember who took it) there was a very faint tail to be seen.  Also if you look at our members images, plus this one from the BBC, the coma does seem to be off centre, so I hope this does indeed mean it is not heading in our direction. 

PLUS I think we would have heard about it by now, or maybe they are keeping it quiet like in Deep Impact!!!

This wonderful, interactive 17P/Holmes orbit viewer Java Applet from NASA's Jet Propulaion Laboratory should put everyone's mind at rest:
