When did I say "all"? I shared my personal experience interviewing web developers in Southern California. And, trust me, it's a good sample size as I've interviewed tens over the years! Also, the HN crowd consists of probably the best software engineers in the industry and that's why HN replaced a lot of aggregated blog feeds and the comments are especially valuable! Maybe I should've clarified that my observation certainly does not apply to the members of this community! :)
