I hope they dismantle it and start over. So many outdated answers on there that I don't find it worth using anymore, whereas it used to be a staple of my software development.
That depends on what stack you're using. Anything based on Linux and Java will be fairly applicable even years later. Even if it's not applicable, it's often possible to tell this from the answer and the date of the question.
IMO, two things would improve matters greatly. One, add a mechanism to mark questions as "potentially obsolete" based on thresholds that can vary per-topic, or per StackExchange site (so e.g. Java has an 8 year shelf-life, general Linux has a 10-year shelf life, Ubuntu in particular has a 4 year shelf life, etc). Two, allow moderators to override an accepted answer after some time passes. I've seen posters not bothering to mark a superior answer later on, or not knowing how to do it. If the community is unanimous about which other answer should go to the top, choose that instead of the original poster's selection.
That's the disappointing thing. They seemed more interested in implementing cute little badges and stuff than working on features that benefit the core function of the site.
If you're doing web development, IMO SO is doing a disservice to people at this point. It's either totally useless if you're a seasoned dev or very misleading and harmful to beginners.
Unfortunately, I'm not sure they have the incentive to really fix things because all the obsolete answers probably still bring in a ton of traffic. The only way to fix it might be to tell people to stop using it.
