I get a lot of shit for those sites -- some fellow HN'ers even told me not to admit to authoring them.
But screw 'em, I spent a lot of time on each one, and as crappy as some of them are, they're my crap, thank you very much. :)
Hackers have a very finely-tuned bullshit detector. I find I can set it off by accident very easily (which is another good argument about just being as honest as I can about these things) I try to explain everything I'm doing and why in blog entries, so no surprises.
You should have seen the post where I tried to explain that scientific research showed that pictures of non-threatening buxom women could double or more click-through response rates across all demographics. I thought they were going to shoot me for that one.
