Users submitting their own websites or blog posts is absolutely normal (and expected). I'd say a previous submission got flagged and with very low karma (upvotes, <5) there was some kind of threshold which puts all new submissions on hold ([dead]) until another user with high karma vouches for it. I'm not a moderator, it's my observation only. Blog post is relevant, just seems to have falled through the cracks when nobody vouched fast enough.
