Questions about odd SERP

Hi guys,
I took the plunge, registered a EMD and started building a little niche site.
When I got it setup with google webmaster tools and did the submissions, it slowly started to go up in the SERP.. I didn't spend enough time I am sure making content, thats kind of my goal now.

But all the sudden I ran into an issue: Google looks like it has de-listed my site almost.
It started to slide down a bit, but all the sudden it disappeared essentially in the rankings. When I check the stats in google, it literally stopped crawling it one day. I have added content and re-submitted the sitemap, fetched the page as google and submitted it a few days ago, but it still hasnt seemed to pick it up, there is no change in the crawl stats and when I look at the number of URL's submitted vs indexed, and they are not matching. Does anyone know why the rankings would just drop, and why it doesnt seem to want to crawl the site anymore? Even with new content it doesnt seem to want to update..

Anyone? Just did some more articles, again it shows more submitted than indexed and crawling still hasnt moved..

Build more backlinks to it. If it's still very new (weeks old), it can happen. The SERPs at that age are completely unpredictable.

Slowly build backlinks to it. Low OBL, High PR.

Alright, starting to do that now.. what did you mean by low OBL?

Low numbers of outbound links. Link from that page to other sites.....

Post some good articles daily and build some good backlinks then google we surely indexed your site.
