Nah I don't assume anyone is avoiding upvoting out of spite or anything, but I just thought HN as a whole was technically more advanced than most other communities because of the user base and niche ... so it leaves me scratching my head.
I've noticed a definite upswing in nontechnical (management, strategy, gossip/politics, worldnews) articles during weekdays in the last couple of years. There are also many more 'redditlike' comments in the last 6 months to 1 year- jokers, puns, easily googlable questions etc. HN community is just changing in that direction as the audience grows.
I've actually been surprised by this assumption - while the community in general sways to the heavily technical side of things; there are plenty of entrepreneurs, idea men, new developers etc - which is great, but definitely something to keep in mind with regard to what the community might find interesting.
It's not a personal attack. HN doesn't have a campaign against you (or if there is one, I wasn't invited).
