I stream 6-7 days of the week, and see a couple of other people who stream regularly as well. I do it mainly for myself, but I have a small group of regulars who come drop by and watch for a bit, and quite a few randoms. The one thing about streaming osu, is that it has a great live spectating system already built in. The one advantage of streaming is that you DO get to have things like a webcam setup and microphone audio. I rather like osu! streams, because you find yourself rooting for someone who is trying to achieve whatever they are doing. If you haven't checked out a stream before, I suggest you give it a try!
