On this site you have the capacity to use a pseudonym....or to use your real name.
You can show an avatar or remain unrecognised.
You can have a profile or you can 'hide' your history and situation.
Why don't people complete a profile? I often want to see what someone does and for whom before answering their question or offering an opinion, only to meet a complete wall of metaphorical silence.
Might people get more ansers if they appear more open about themselves?
