It's not hard to find others with problems. Look at the McElroy podcast archive: they alone lost numerous episodes because Audacity just didn't record any audio. My podcasting friends have ended up with corrupt Audacity save files (sometimes after a crash, sometimes just because), requiring a painful recovery process involving stitching together hundreds of scratch files.

If it were just me, I'd agree with you. But it's so common that I don't consider it a viable way to edit audio.

Edit: in thinking about it, one of the friends I record with often actually records with both Audacity and another app, just because Audacity fails so often.
