No, my phone isn't rooted. I'm just using the stock hotspot app.
I was into rooting a lot when I had my OG Droid, mostly for overclocking. But I've really not felt a need to overclock a phone since I had the TBolt, and I actually like Sense, so I'm not looking for another ROM. And being rooted can be a big PITA at times, like getting OTA updates for example.
