Google is good. The search engine that is. Not just good, it's brilliant. So is GMail. I'm a GMail user from the very beginning and love it. So are many other Google services; they really have set some standards. However, Google Wave is just not one of them.
Simply put GW is more or less a hyped up chat program I think. Fancy name, cool interface, and more or less all the forms of media we know is put together - except voice and video chat. So basically you can text chat, add some pics and/or vids to it. Oh and also you can Tweet and Blog from within it, but that's just about it. I can drag-drop an image or a video to Skype and do the same - watch it online or watch it after downloading, they're all the same after all - plus I like the much simpler Skype interface. So yeah, it'll take a bit more for GW to make me a fan. But then again as much as I don't care about GW, I'm damn sure they don't give a crap if I become their fan or not either.
