This old question is about a cleric who wants to speed up his casting of divine spells. By our current standards for asking and answering, answers should respond to that exact situation and offer options which help clerics speed up divine spellcasting.
However, it's also a textbook case of a user asking about their specific situation in very broad terms to be useful. In this case, they expanded the question to ask for all options to speeding up every kind of spell. That really is what happened; they even considered it a mistake to mention they were a cleric:
P.S. I see a lot of requests for more information on my character. I was hoping to create a question that more people would find useful (I guess I shouldn't have mentioned that I am a cleric either ;-) ).
The answers are messy as a result.
Most go into Cleric specifics without worrying about stuff for any other casters. Others mention things that explicitly only speed up arcane spell casting, which whilst useful is irrelevant to a cleric.
Hey I Can Chan then posted this excellent compilation of effects that speed up spellcasting, but a great number are completely irrelevant to clerics.
By our current standards this is all over the place. They're answering two different situations ("What things speed up spells?" and "What things speed up cleric spells?") because of how the question was asked.
What do we do?
Do we leave this messed up?
Do we somehow split the answers into a canon question for speeding up Divine casting and a canon question for speeding up anything-casting?
