I would have to agree with you there, QWEST. In several years of participating in and running online communities myself, I've seen MANY people who don't read, but just ask questions, and you either let it roll off your back or you get frustrated. Life's too short to get agitated every time a new person asks an old question, and I'm telling you this as a person who has a short temper and the curse of being a perfectionist.
It honestly takes less time to link someone to a post that answers their questions than to type the fact that someone is the 1,000th person to ask the same question that day, as frustrating as it may be. Besides, that's what we had IRC or staff forum sections for, so we could complain in private, rather than risk making ourselves look like jerks.
Trust me, I know so many of you have answered many of the same questions over and over, but when you get that 1 person out of 10 who becomes a helpful and contributing member, it makes all your effort worthwhile.
