Most Helpful Guy
If, after 30 days, you haven't chosen and selected a Most Helpful opinion, one will automatically be chosen for you.
Neither the Question Asker nor the user awarded Most Helpful will get Xper points for these automatic selections.
It's chosen based on engagement: votes, comments, length, time, xper level, gender, among other criteria. As long as you're giving helpful opinions, we'll find them!
This is to encourage everyone to choose a MHO on their own, making sure people get the credit they deserve.
