Thanks for observing, I've added this to the bug list and we'll get it fixed.
It appears that the category has been removed or renamed. It does not appear as an option in the Categories of Page Management. The 404 error should have logged on the web server.
Should be showing up in someones dashboard. Selecting Hacks from the Mahalo homepage does not reflect a new name, just the 404. The subtopics still work.
Perhaps some there is some category cleanup going on.
Actually I have no idea. Probably because Mahalo expects a SERP (search enginge result page) but it can't find the right page. The best way to solve this is to send an email to contact@mahalo.com It does happen sometimes.
This is another example that gives a 404 http://www. Mahalo.com/category/javascript.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
