And there's a good amount of information that still apply. Things like "living beneath your means" lessons, "what will I do with my time" suggestions, and so on. I think it's also good not to lose what people did during the last recession.
I think one should check all information here, whether it's 10 days old or 10 years. Not all info given here is factually correct. When I search for info here I check the date of threads as part of my appraisal of information. And occasionally someone will revive an old thread, but they do get a warning when that happens (and hopefully don't ignore the warning without good reason). Otherwise it seems very easy to avoid old threads and possibly outdated info by not going beyond the first few pages of a forum.
