I used diigo for annotation before clearly had highlighting. Now, just as you, use diigo for link storage and Evernote for content storage. Diigo annotation has still the advantage that it excerpts the text you highlight. With Clearly if I want to have the highlighted parts I have to find and manually select them again... Also tagging from clearly requires 5 or so clicks which is ridiculous... But I hope it will get fixed.

I plan to use pocket once I get a tablet... it is pretty and convenient, but the most likely to get cut out of the workflow.

Thanks for the evernote import function - I'll look into it, maybe it could make the Evenote - org-mode integration tighter. Even then, having 3 separate systems is not quite optimal...
