Algorithms.

Don't know if this is the case here, but if a mod notices something interesting and it doesn't gain traction, they will invite the submitter to submit it again at a later date and add a bump to keep it up a little longer to see if it gains traction then.

It's nice that there is some variety of interesting things here so that it's not all tech-related. Most hackers love cats I think.
