Picks are a way to state your opinion, または just find out what other people think. あなた might post a pick to find a new icon, または other's お気に入り foods. I like the way あなた can sometimes add a choice, which makes your opinion different.
Picks may also work as a school project: Example:Question: do あなた have a brother/sister? Project: take a survey and see how many people have a brother または sister.
Picks are a way to state an opinion without starting an argument, または sometimes they are not to state an opinion.
Adding 画像 to picks is fun,too. some 画像 are goofy, others can really fit in. It is creative to add images, and some times important, such as if あなた ask, "who's cuter?" you'll need to put 画像 on the pick.
I like picks becuase they really are a way to state your opinion. They are a reminder that everyone has an opinion.
And that is why I 愛 picks.
