@Jas. 3.1-What are you after, anyway? Voting is somewhat subjective, based on what an individual values 'quality'. I can list a number of criteria that might produce a 'quality' answer, but I find the 'Mods'(or those that act like them) do a fairly good job in screening the 'dreck' from the pool of answers that come in.
Beyond that, I find selection is very 'subjective', depending on what school of theology you come from. I find 'post modernist' presentations, although very "scholarly", suitable for wrapping fish in. Others find "Doctrinal Assertations", even with "proofs" 'anathema', they simply can't conceive of anybody knowing anything 'concrete' about God. I believe what we have is a smorgasbord: some like the letkes and the krumkake-and leave the lutefisk.
The quality of "great" answers I believe rises when people: 1) Answer the Question(not just voice speculations; 2) Are on Topic and in Context; 3) Provide credible and convincing support for their conclusions. Beyond that, good writing skills help, insights that contribute to understanding the question involved, scholarly applications where it isn't 'oppressive', and a dose of humor which engages your listeners.
The 'Powers that Be' might consider a "Best of BH"-a take off on "The Best of Craigslist". You can be 'subjective' yet take in a variety of answers which qualify as "Good Answers" without subscribing to their theological slant.
