I can send a document to my kindle (app/device) by e-mail.
I can send a document to my Evernote account.
I can’t send one to Google Docs by e-mail anymore. Used to be able to. Not anymore.
So, I basically found this out when trying to send something to my Google Docs writely address this past weekend (hadn’t used it in over a year). The address was useless. Google folks say they are working on improving the feature. Probably going to have to email a document to your circle before you upload it to Google docs.
