Is there any way to view the number of users online at any given time (or even an approximation)? This could be really useful to provide an indication of whether your question is likely to get answered any time soon.
It could also provide a bit of an indication for why your question is getting very low views - if there are only a few users online, then that could be the reason for little interest in a question, whereas if there are lots of users online and the question still doesn't garner many views, then maybe it needs to be rephrased or something.
I know that this can't be used definitively, but it could be used as a rough guide, and could also just be an item of interest. Perhaps it could show the number of users that have been seen in the past 5 / 10 minutes? (Shouldn't be too hard, since each user page already shows the last time that they were seen).
