I've read a lot of good points in this thread. I play in DADGAD a lot. Not because of treating the tuning like I'm on some holy quest (I've met a couple people who treat it like that) but because I'm lazy. I liked the sound, but also became aware of the limitations. I like working around the limitations. I find playing in F is easier than in standard, for example. Partial chords are my friend. At the song circle I used to attend I would accompany a lot of the other musicians, who were playing in standard, with single note fills, sometimes capoing to whatever fret they were on, or just playing uncapoed on the notes that sounded good. No one ever asked me to not play along.
