Although raindrop is still under development, it is a very good bookmarking tool. I can't say I'm anything close to an expert nor have I tried their competitors, but I would absolutely recommend not only the free version of this app (which gives EVERYTHING you need, with the exception being nested favorites), but the paid version is only 3 a month. (You DO get nested collections with that, not to mention a bunch of other goodies as well.) The devs offer the ability to vote on what feature should be implemented next, and that means a lot to me as a consumer. I've had firefox completely delete all my bookmarks before, YEARS of stuff just lost. But raindrop had me covered, as I had already imported all my stuff in there.

Its really only going to get better as time goes on. If I could complain about 1 thing, it would be the ablitity to organize WITHOUT clicking and dragging. As in "move item 101 to position 3". Because it will make you drag something from a list of hundreds all the way to the top, and don't slip up, or you start again. That does suck.

Nevertheless, I wholeheartedly recommend this addon, and I do recommend spending the 3 bucks a month on the pro features too. It will make it worth your time, especially for those of you interested in game design or journalism. The amount of things you need to link back to in those fields is an honest nightmare, and I'd die without a software like this.
