I guess this has been discussed on other SE sites, but I'm interested in the opinions on cogsci.SE specifically:
I feel this site misses a system to send private messages to other members.
People who commit to a site and become members of its community, sometimes want to interact with the other members on a private level. There is a chat here for that, but not everything wants to be said in front of an audience (One member said to another member: " I think we should get divorced."), some interactions are too short for a chat ("Thanks, love your answers!"), and – how the heck am I to let anyone know I want to chat with them without posting off-topic comments or lingering in chat for hours?
Private messages bring other problems (such as having to reply to them or appear unfriendly), but if we really want to limit the answers and comments to being on topic, then private messages are a way to release the need social interaction.
I wonder how other members of cogsci.SE feel about this.
