My preference for edit time is 1 minute per line, up to 5 minutes total in Politics or Congress. (I have truly caught some completely unintended gaffes on longer posts) Sometimes the other poster puts up 12 to 20 complex questions/talking points in a post then rants if someone only addresses one point, which can take a lot longer to address than it took its author to throw it out. Just sayin'.
I'd like to see longer time limits for when one is writing poetry or haiku. Sometimes sleeping on it when you write a verse truly helps the improvement of compositions. I don't know if this could even be done by thread managers. I have to write my metered poetry elsewhere due to time constraints on making corrections. If I try composing a longer verse here, the board nanny kicks me off and I have to long in again. I've lost posts I spent a long time working on to answer someone's complex talking points post. My computer isn't that slow, but lately, there have been a number of political omissions from the face of the internet a lot of information, and wikipedia is no longer my source of choice due to its extremely rewritten historical media bias that fails to be true. It takes too much time to chase down links that relate to what the headlines or even what government sources were just 5-20 years ago. It is often replaced by sophomoric contemporary lockstep political hype on both sides.
*sigh & wishful thinking*.
