Because every interaction with your friends has to be serious or deeply thought out right? There's no room in this world for a quick, casual hello or chit chat!!!!!Dice said:I don't understand the post-it note sort of stuff like on someone's wall. Those frequently turned into half-assed chats. If it's going to be serious, write an email. If it's going to be conversational, have a conversation. If it's something small I need to know, text my phone so I don't miss it. A little note on a wall is the most socially vapid and useless thing.
The lack of a wall is one of Google+'s flaws. Your profile is completely static and if someone's looking at it, there's no way for them to interact with you from there. They have to go to the "sharing area", type out a message, and specifically name you as the recipient. And the only place you see it is in your news feed.
