In this answer on Meta.Islam.SE, Caleb essentially suggests that summarizing the response of another scholar is an inappropriate answer for a SE question. He says
If you can actually research the subject until you understand the issue and can formulate the answer based on your own knowledge and use the sources you studied as external references then by all means jump in.
This does not seem to be the typical rule that we follow here on Mi Yodeya. Over here, summaries of teshuvas by rabbonim that address the question are typically considered good answers. We don't generally go for answers written by members of the MY community without some evidence backing up our assertions.
Are we just different from other SE sites? It seems to me that we need to have some kind of authority behind our answers over here. Otherwise, it's just some person on the internet saying what he/she thinks about Judaism.
