I would really love to have an iPhone app that allows me to read and comment on HN (as opposed to just browsing with Safari). Something similar to the SFNetNews app for reading Slashdot, etc. I was thinking of writing one for HN since I haven't been able to find one and I figure it will be a good first-iPhone-app for me. :)
