I have had some time off recently so I concentrated on my pet projects. One of these being a "mapper" to find people who are similar and group them together. Its working quite well and the php frontend is very easy to write. So far I have just made up some little pointless questions (a lot of them were submitted by others). Strangest thing is the correlation between the different maps.
For example this is a map of Tea (blue) vs Coffee (red)
It has a very similar layout as the C (red) vs Java (blue)
