Considering most of the HN population are technical folks, many will possibly find your experience & knowledge useful or at the very least, contribute to a worthwhile discussion on hiring technical people.
Edit - Added a list of problems/mistakes that I commonly see when I interview people for technical positions:
• Being borderline arrogant, argumentative and/or abrasive in conversation even though they are brilliant - Yes, I've interviewed people that are smart and have a wealth of knowledge but the straight forward truth is this role (and most developer/engineering roles for that matter) requires a person to work with not only other people within the team but also with other technical teams & departments so if you can't show that you are a team player, it doesn't matter how good you are as a developer/engineer.
• Lying straight up on certain details and not owning up to it - one common interview tactic I use is to ask what version of [technology] that the person has worked on and what are their "battle scars" experiences with that particular version or [technology]. I have had people tell me they work on versions that don't exist (i.e. latest v5 and they claim v8) or claim they have 5 years experience when said version of [technology] has only existed for 3 years. Also, I find that the true experienced people in [technology] can passionately tell you about their problems using [technology] and what they did to get around it rather than simply just evangelizing said [technology].
• Talking bad about anything or anyone - This might just be a personal preference but a big turn off for me is when a candidate starts bad mouthing their ex-bosses, colleagues or company. I might make exceptions for special circumstances (i.e. sexual harassment, bullying, etc) but even then, I will find it as a negative against their personality if that person keeps harping on it and don't show at least signs that they are taking steps to move on. Call me old school but I believe in never burning your bridges regardless of what the circumstances are and even if you don't, the last thing you should do is bring it up in an interview.
Note - these are my personal opinions, preferences and experiences on interviewing and I do not claim my methods to be the best way on doing so.
