Looking at the HN homepage now, many are what I would consider blatant self-promotion and border on spammy. Granted, I have no problem with someone wanting feedback on their site or offering a really in-depth look at internal technology (e.g., this is how we handle failover and scale to 1MM uniques/day), but a lot of companies just manufacture reasons to blog solely to boost traffic (company memo: thanks for the blog ideas and upvoting our post, HN gave us 10K hits today! good leads!).
HN page as of now (50% are self-promotion, several IMO are legit): 1. Neural Networks for Machine Learning (coursera.org) 3. Keccak wins the SHA-3 competition (nist.gov) 5.
