I can certainly see that there's a lot of add-on guff for Flickr (and like sites) for those who have lots of time on their hands OR actually have a real NEED to be filled - stuff that they could certainly make use of.

I'm sure if I ever have the need, there will be an application etc etc out there to fill it.
