This was kind of inevitable. Google Dictionary, I mean. It's a straight-up dictionary, yeah, but it has a few pretty Google-y features, like the ability to star words, if you're real forgetful, and you can search for words in multiple languages. It's also a fairly stripped interface, unlike a lot of dictionary sites, which is what I find most appealing.
Though I'll probably keep doing what I usually do, and just plug words into my browser's search bar when I wanna know what it means—why bother going to a separate dictionary site? [Google via LA Times]
