After the stackoverflow question clean-up exercise, i found the old interview questions threads that were popular and highly regarded back in the days to be deleted as well (can no longer find them - dead links). Naturally, my answers and others' went down with them. Which means, I no longer have a "permanent" page to revisit for reference nor tell other folks to read through.
Perhaps those threads could have beeen moved to the programmers site?
Example question in discussion: Identifying passionate programmers (see if anybody else can actually see that anymore?)
