If you don't use facebook, twitter or blogs you won't need this.
Not all true,
Its a very powerfull email and IM tool.
The options with Wave are endless!
I think this is better than sharepoint tbh, with the editing, being able to see online edits ect, also IM + email built in.
Anyone use Photobucket/flicker? its replaced with this app too. BUT with photobucket/flicker adopt the API's they can merge into wave, so you can upload your pics/videos through wave and they appear on your accounts.
Its taking an unlimited amount programs and websites and turning into one app/web app for editing/adopting/publishing.
If it works and gets taken up its gunna be a good start, expecially with the approch of here is the API's go develop! with other new dev project this never happens.
Google are gunna use the opensource community to push there product into the world and I can see if people don't see it as a pain this is gunna take off bigtime.
Until the developers start to get to grasps with wave its gunna be a slow road, one its got a backbone with developers its gunna be really good.
Personally i can't wait for the Blog support! being able to read/see/edit multiple blogs from with in 1 app.. no complains there!
