We were contacted today by the founder of the soon to launch social network for gay men BigJock. It lead us to take a look around the gay male online social networking space and write the following overview of some of the current market leaders. Niche social networks are likely a viable business because they allow specialized functionality and a subjective community feel as opposed to general interest sites that defer to either the lowest common denominator or the year old demographic. Many people want to participate in social networks, but many people prefer networks set up for people they can relate to. That makes sense to me.
