Please bookmark/pin https://web.skype.com to enjoy Skype on your Chromebook
Skype comes as a pre-installed application on the google chromebook. If you don't see it you can download it from google chrome webstore.
Hope this helps.
I have looked on the chrome store a billion times and havent once found a skype app. I have found something to see hidden friends but not Skype itsself.
You are all right. I was mistaken, they are working on a working skype version on google chromebook. There is a work around though but do not think you can vmake voice calls but can video chat (I have not tested this but thought I could pass the information along).
https://plus.im I was able to sign in successfully with this. Other work arounds include microsoft's outlook.com that has skype integration and skypeface that you can use to make calls. All can be downloaded at the webstore. I have attached a link here webstore.
Hope this helps and sorry for the added confusion earlier.
Google has a similar product called GoogleVoice but I don't think it is a available worldwide as Skype. I suspect MS and G are not playing nice so you will likely need to use GoogleVoice. It is free to make US-US calls through 1/1/14
