Reddit's spam filter is completely broken with no apparent activity from the current group of admins towards fixing it.

It seems that generally if you submit something to reddit, it will get caught in the spam filter, then you have to message a moderator to request that it get approved.

[Again, it seems] that you're not so much voting on an assortment of links, you're voting on an assortment of links that moderators have deemed worthy.

EDIT: Right now that submission has 5 points, from people who must have clicked through on the blog post, and one comment complaining about how it's not about programming, also from someone who must have clicked through from the post.
