My profile links to my Flickr account, which has my real name. I don't currently maintain a blog or anything more meaningful to link to. I use this nickname throughout the net. You can email me at <pick anything>@lusr.org. I'm not hiding anything.

The person I responded to frequents HN (according to their own words); it seems highly likely they know quite well how non-constructive their response was and specifically chose to use a throwaway account rather than stand behind their comment under their normal account.
