Image via CrunchBaseWhat do you get if you combine Twitter and listening to music? What you get is Blip.fm, a social site where users DJ for each other. I have been playing around with Blip.fm for a couple days now and am finding it a great way to discover new music, hear songs I haven't heard in ages, and get acquainted with others through their musical tastes. If any of this sounds interesting, check it out. You'll find me there as vjack. Just be forewarned that if you love music like I do, it can be pretty addicting.
