You know what's really hilarious? I still use Second Life sometimes, which at the time received a certain amount of mockery because people were in effect using a huge, bloated 3D application for text chat. Thanks to the wonders of modern web technology, everyone's caught up in the bloat department so that Second Life's not actually much more RAM and CPU hungry than alternative options for text chat. Even though it's streaming and rendering a whole 3D virtual environment in real time.
