I've messed around with lots of bookmarking services, but none seems to do everything I want. I just want to be able to drag and drop anything and have it saved for later, and now I'm just using a stack on my OSX dock:
The Stack is just a folder in my home directory, but it could just as easily be a shared folder in Dropbox or Drive, and it supports anything that you can drag and drop in OSX. There's not really any metadata, but if I really need to know where a picture came from I can google image search. I dunno. Thoughts?
