Someone who clearly invested some effort in formulating their question, for example because they indicated solutions they tried and failed, and who clearly document their problem (eg. schematic/pictures) are unlikely to need spoon feeding. That definitely motivates me to invest more time in helping them than someone posting 'How do I hook up a LED?'
You have a point here. However knowing something very well, makes an experienced person have a "distorted" idea of what should have been done. In the software world, when I have a question I usually can formulate it exactly as needed and I will usually get a precise answer. However in electronics I get very swamped very easily and forget to do even the most basic like checking a datasheet, or check the proper section of a datasheet. It is an elementary mistake and I might get an arrogant answer for it (hasn't happened here, but I'm sure you know what I am talking about), but it just happens and has nothing to do with the attitude of the asker.
This I find sad, and I disagree. I have actually found valuable information by searching this forum, and think that the forum archives are an important resource. For example if you're wondering if Hakko soldering stations sold by DealExtreme are genuine, you may find tear downs and discussions on this forum. If you're wondering about heating element quality between Hakko and some knock-offs, then you may find that someone took the time to compare thermal recovery between heating elements. If you're wondering about a split versus solid ground plane, then you'll find that someone built two boards and posted measurements. Some of these posters have invested a significant amount of time in those posts. It's not really fair to expect these people to repost this information every time someone new comes along.
Granted, I have found precious information, I'll give you a counterexample. I have a rigol ds1052e. Hackable to 100mhz. Actually you have to read tons of posts spanning to 3 versions before my current firmware version. Does it contain the info? Yep. Do you trust the info without reading absolutely every single post? Nah. The threads themselves serve a wonderful purpose, which is the actual hacking (and I actually LOVE to read them for amusement). But I am not intersted in actually hacking it, I want it to be 100mhz and move on to other projects. Selfish? I'd say better use of our collective resources, if I don't use the time to do that I might have time to make some other project which might help the community.
(Funny thing on the above. I might even be wrong and there is very good and precise info on this, but I just can't find it. This is my point)
But if I want to know whether I'm wasting those $300 by buying that particular scope, I consider it my job to dig through that information, not to ask someone else to do it for me. The more experiences I read, the better I know what to expect. It's also often non-trivial to summarize a long thread.
Yes if you(we) are a sum of individuals. But as a community, isn't too much time wasted in this? Wouldn't be better to just not have to answer any question at all?
Yes, some things could be better stored on a wiki. I don't think the EEVblog wiki ever got enough momentum and participants to really become useful.
This is just an idea and probably not even the answer to everything. However, you don't need to build the new wikipedia. Check the OpenWRT wiki, you will get what I am talking about. Altough I haven't used it for some time, I remember finding everything I wanted fast. I hacked my router, added an sd card, new LEDs, unbricked it a couple of times via JTAG, and I didn't even have to ask a single question on the forum.
Are you volunteering your time?
Now you are just getting defensive.
Actually you are already volunteering your time by answering beginner questions and so am I (well...If I know the answer). Everybody is obviously free to use their time as they please - and I'm sorry if I sounded as if I was showing you how to use your time - but I find it much more efficient to just write a wiki than answering the same question 100 times. To answer your question, no I probably don't have enough time to be pivotal in the making of this, but I would most probably help to the extent of my knowledge (actually I would be more useful in providing hosting/administration).
One last thing...I don't want to show you how to run this place, I actually love it as it is. Nevertheless it's fun to stir things a bit.
