Most forum sites these days have at least a link to Share on Facebook,or twitter updates showing on the sidebar but QB seems to still be going at it old school. As much as old is gold my brothers I think we need to embrace these things if we want to gather followups. Being a SEO specialist,I must say facebook and twitter will bring you much more traffic through sharing and FACEBOOK CONNECT.
Test your fate in the waters of spontainety,and you shall realise that the universe revolves around you.
