Google Wave: It's everything for everyone, for those who have it.

Google wave is awesome. Awesome because I've watched all the videos, read the hype and can't stand to live without it. Yesterday I got it. My immediate reaction was to enjoy it while it lasted because this was definitely the second coming and soon everyone around me would disappear leaving me nobody to wave with.

The problem I see is that you can only communicate with other wave users. If I still have to go to gmail to send an email to a non google wave user then it's pointless. Why do I need to have two email accounts? Not everyone is going to use google wave, even when it's freely distributed and available to anyone. My girlfriend still uses a yahoo account even though Gmail is much better. It's what she's used and she likes it. Guess what? I doubt we'll be able to ride the google wave together.

Unless I'm horribly mistaken or google ads the ability to send messages to people outside of the google wave system I'm afraid it won't replace gmail as my primary communication tool. If I am wrong please let me know in the comments!
