Some (not all) of the services listed seem like they could be very useful but I am verging on the sceptical side. Perhaps clarifying these points will ease my doubt: 1) Who is behind this? I can't find this information easily on the website. 2) How and where from are the testers acquired? 3) Do I receive any demographic data about each tester? I.e.: location, age, etc... 4) Has anyone here tried using any of these services? |
