Legitimate question: why is it inconsiderate? I've actually had some decent exchanges with people on zombie threads. And you can barely start a thread on this site without someone saying "use the search function". If zombie thread elicits a question, what's wrong with throwing it out there to see if that particular member or perhaps someone taking a look at the new posts might be able to weigh in? I've had good advice about pickups, tuners, set lists, lots of stuff from the zombies. But if it's inconsiderate, well that would violate one of the general tenets of my existence, which is to try to be considerate. I'm just having a hard time figuring out what exactly might be inconsiderate about it.
It's inconsiderate if the new post serves only to trick people into wasting time reading a long out of date thread, and the zombie simply goes back to sleep because no new content is added.
All I am saying, is if you're going to wake a zombie, make it count. Don't make some snarkey comment. Don't introduce a new topic that doesn't relate to the zombie in any way. Don't repeat answers that have already been given in the thread; especially to people who have not logged on to Talkbass in years. People wake zombies in this way all the time.
IMHO if you have a question, most of the time it's actually better to start a new thread. When you wake a zombie it shows up as activity in the Active Today and Latest Posts threads on the home page. People see this and start reading from the beginning of the thread instead starting at your question. Only people who are still subscribed to the thread will get an alert and go straight to your question. If the thread is really old, most of the original subscribers are long gone. Also as threads get longer and longer, they often spiral off topic, which can encourage most people to unsubscribe.
IMHO some good reasons to wake a zombie: To give new info that was not discussed in the thread, or cover the discussion from a different angle that corrects misconceptions presented in the thread. For example sometimes after I have read through an old thread, I may add a note with a solution that was not originally explored. The idea is to correct the record for anyone else who uses the search feature. This sometimes gives an old thread an extended new life.
The GOFs who jump on everyone who wakes a zombie get on my nerves as well. But I see their point, because most of the zombies that are disturbed should be left alone.
Anyone who jumps on a newb for bringing up an old topic is another story. I frequently try to correct this behavior and suggest either ignoring the post or logging off. Newbs should be encouraged to ask questions and participate as far as I am concerned, as they are the future of Talkbass. IMHO it's okay to suggest using the search feature, but do it in a positive way and I suggest including examples of good threads and the best way to find them. IMHO Google usually works way better than the Talkbass search feature.
