I guess the main reason everybody ends up here is that Mudcat has already accumulated a huge amount of information and it's all searchable.

Reddit, by comparison, doesn't have a complete search. Imagine being able to search only the title of a thread and the first message in each thread. That usually means that a question is searchable but the answer is not. Also, every thread only stays on the front page for a day or so and then it disappears forever. You can still find the thread with a search (provided, of course, what you're searching for is in the title or the first message) and for the first six months, you can add new messages to it, but the thread will never be "refreshed," that is, it will never appear on the front page again, so nobody will know that you added a message (unless they happen to find the thread by searching for it themselves). Therefore people almost never bother to search for old threads or add messages to them. People keep starting new threads about popular subjects all the time. There is a lot of redundancy, and a lot of turnover of members. People don't work very hard to do research, either, knowing that whatever they post will disappear almost as soon as it is posted. Reddit is fine if you only want to have a conversation and then you don't care if your words will never be seen again, but it's terrible as a place to try to store or look up information.
