The Professionals of musical or dramatic interlude are not the pro's this post will address. It was noting that LinkedIn is the only professional social network (as opposed to unprofessional social network) to rank - and at #24 - that flung me out on a search for others. The search as per hyperlink above produced these contenders:

• CompanyLoop
• DoMyStuff
• DOOSTANG
• Fast Pitch
• Konnects
• LinkedIn
• PairUp
• Ryze
• Spoke
• XING
