This is super cool and I've been thinking about building something like this for a long time. One thing to also consider: timing data. In my thinking about it, I thought that it would be massively useful to record both the exact time and order pages were visited in, and the other tabs open at that time. Lastly, check out AlchemyAPI to auto-suggest some tags / keywords based on page content to make recall easier. Basically this + all of the above + a browsable timeline interface was my idea. Please take it and build it if you have the time / motivation, and I'll subscribe to your service (or help hack on it if you open-source it). The best competitor I've found so far is Pocket with the premium features (I'm a subscriber). Good luck, and great work. I also love meteor and ES :)
