So far, the voting personality seems to be significantly different this year

Just from my own observations,so far, the voting this year seems to be taking on a new personality.  For example, there seems to be a much steeper threshhold for acceptance. Conversely, the number of ideas with double digit negative scores also seems to be somewhat lower. Also, a few remaining ideas left from previous top ten lists don't seem to be getting the same level of attention this year.  Commenting on ideas also seems to be down a bit.  Any thoughts about all this, or is it just preception?
