I just mean those for fun, sometimes helpful as well, few good advices there but they have a support forum for those willing to change & improve (I guess people with problems, it's explained there on site, don't remember which university related).
I just do it for fun and give to friends so we can have a good laugh, but can be useful as well, just don't take the results very seriously (there is always hope, even if you get "bad" results, life goes on and can be better, always)
