Well that’s where you lose me. As has been mentioned at least a few times, some people prefer reading and writing in a more informal thread like this one. If you’re concerned that it will make your search engine less effective, that is one thing and certainly there are ways to focus the search tool. But by removing this thread in an attempt to force people to use/create more specific/technical threads, you would be making this website less enjoyable for some (many?) members.
It reminds me of something my grandfather used to tell me all the time; “There are 2 kinds of people in the world. There are sprinters and there are packers. You can force a sprinter to carry a pack but they won’t like it. You can force a packer to run but they will never be very fast”.
It seems to me that the main reason people use a site like this is for their own pleasure. By forcing people to behave the way you would like, you will probably drive them away. The fact that some information will not be readily available in a search is unfortunately the way life is… (my grand father also used to say "Life is messy".
As a leader/administrator, it is important to recognize if you yourself are a packer or a sprinter (I suspect you are an organizer and like neatly formatted information). Once you know this, the real challenge to being a successful leader is to recognize the value of those who don’t think the same way you do, and then, make policy that still allows everyone to enjoy spending time here. Hopefully the monthly version you are starting will do that.
