Hi,
I bookmarked a while ago this thread: https://news.ycombinator.com/item?id=29606476
with the intent, that if I'm going to Munich again, I'd maybe propose meeting up for lunch (I have bit of a similar background as the OP).
I'm going to Munich next week and wanted to follow up on my idea. Responding to that old thread seems to be disabled (HN policy?). Can I resurrect commenting or reach out to OP somehow?
There's no way of directly contacting a HN user unless they post contact information in their profile.
In any case, the author of that post hasn't posted any stories or comments since then, so they may have left HN entirely.
