This is a complex subject and one that I have studied for over a decade after having my own close encounters. It makes perfect sense to me that reports increase with increased use of the internet, since the process of making reports is dramatically simplified by the web. None of this, though, can be easily shown to have any direct relationship to the actual number of real UFO sightings being experienced - since that figure is not known.. We only have the amount of sightings being reported.
