People are resorting to Google search when it comes to knowing about the person they are chatting with. Googling, if not anything gives a sense of safety in the process of dating. Also, you get to know more about your date in some way.
But it's not always advisable to Google the information about your guy as this may ruin the surprise factor of the conversation you'll make.
Also, you might, as a result of what you see on net, may get biased about the guy. Wrong assumptions may lead you to jump to wrong conclusions about the guy.
All this may end up into a wrong way where you may end up cheating yourself amd him as well. So, be aware, but avoid googling.
