The Swiss Army knife is an engineering marvel. Encapsulated within its small frame lies all the bare essentials you need to survive. I have one in my pocket right now, and I can't begin to tell you just how useful it has been for all those times I've needed something cut, opened, unscrewed, filed, or punctured. But when it comes to being online, I'm perpetually disappointed. There are few such all-in-one tools at my disposal. Wouldn't it be sheer bliss if the Swiss Army knife had a digital equivalent, a Web site that had the tools necessary for online survival in one place?
