The worst are the ones where some new mod has trolled through four-year-old questions closing them whenever possible. Makes me wonder how much great information has simply been deleted to give a new mod, what, a feeling of power? More history (ironically)? It's also darkly funny when a mod clearly doesn't understand the technology involved, and thus doesn't understand that it is, in fact, valid and properly worded.
I suppose it's no different than the rest of the tech community, "blogosphere", social coding sites, etc., where it's a self-promotion-centric approach that dominates. You'll get further working on the latest and greatest stack than you will solving hard problems with an older tech stack.
