Given the (quite understandable) confusion over this site's scope, as well as due to convincing arguments by Gilles, and Jason's and Wipqozn's concerns with regard to low-quality answers by definition, I think we should consider switching this site's title to "Everyday Living."
Idea taken from this post by Gilles
I think this is concurrent with the questions left open on this site at this point. The largest benefits in this change, in my opinion, would be that the purpose of this site will be immediately understood by new contributors, and the usefullness this site has toward most of its users, the casual Google readers, estimated by Gilles to outnumber LH contributors/registered users.
To counter the argument that this makes the site a "catch-all," I don't believe it would. We've already limited the site to physical, everyday problems, and we won't take questions that are about, say, programming or programmers, religion (1, 2, 3, etc) or co-workers. The questions asked here now will only be about physical problems encountered in everyday life.
Heck, any of those sites I just linked to have pretty broad scopes; maybe we should shut down SO, for example, because not every user who knows Java will have anything worthwhile to add under the C# tag. What ties together the scope of SO is that it all has to do with programming -- I would argue that the same can be said here; this site's scope is physical problems that can be encountered on a day-to-day basis.
I do realize that this change is more than just a symbol -- it will also, of necessity, change the way that the contributors and the (relatively speaking) long-time users think of the site, and the answers posted -- we will no longer downvote conventional answers, the definition of on-topic questions will change (though it will become a lot easier to understand, IMO), and What is a lifehack? will become a moot question.
The only downside I could think of, offhand, was that this still leaves the problem of Who are the experts? unresolved, though this site always had that problem. I think that we'll just have to make do, in the way that Superuser does: the guys with the most fake internet points on the site are the experts.
To clarify: hack answers are still cool and very much expected -- this is, after all, what we're here for, right? But at the same time, to make this site useful to the internet (the greater purpose of why we're here), why (borrowing words from Gilles) should our questions implicitly exclude the best answer*? That's just not useful to anyone.
