Just want to chime in and say that I've been using Stache for a few months and, aside from some syncing issues (especially on new computers with the first sync), I've found it to be really enjoyable. I'm hesitant to say I've completely moved from Delicious, mostly because I'm struggling with the app vs service thing, but it's a great experience. Very glad to see you've taken advantage of Safari extensions, which makes the iOS version a thousand times more useful. Awesome work, guys.
