Would you count them as spammy and disavow?

I am pretty sure that the mobile version of the main site needs to be the same canonical link from what I understand. I am trying to find good docuementation that supports this. Even better if its from Google or Matt Cutts. I have a main domain like http://www.mydomain.com the mobile version of this is http://www.mydomain.com/m/ Should my canonical be rel="canonical" href="http://www.mydomain.com"/> for both these pages?

I am going to build a fake product and wanted to get some of your awesome ideas 🙂 This is for fun, laughs and mainly viral/back links. Ultimately my goal is to leave the user scratching their head saying to them self "Is this for real?". I want it almost believable 😉 First: My site is based on everything scrabble so I want it related to that since my fans are going to get a kick out of it. I need some great starting points of something fake I can create and post about.

My question is I noticed today that the snap shots of my main pages were outdated. About a month. Then I clicked on the "Learn More" link about cahced images and Google says "Google crawls the web and takes snapshots of each page. When you click Cached, you'll see the webpage as it looked when we last indexed it." I know this sounds really dumb, but does that really mean the last time Google indexed that page? So the changes I have made since then have not been taken yet?
