neonmonk 

A pedantic person who delights in being critical of others but produces nothing original of their own, who spends their life on irc chat channels to point out the flaws in other's typing, spelling and logic. Derived from Neon "A tasteless, colorless, inert gas" and Monk "a male religious living in a cloister and devoting himself to contemplation and prayer and work"
