johnnydequino, most likely is that the page was down when we tried to crawl it. That just takes times. Scoring changes can affect rankings, so I normally do a search like
site:yourdomain.com -asdfsdf
to see if we have pages from that domain. Last thing that affects only a tiny number of people is that we respond to complaints about sites, so if a site is outside our quality guidelines (e.g. cloaking, sneaky redirects) then that can cause problems.
More Traffic Please, I'm not going to speculate on what the future holds, other than we're always going to be working to find ways to make search more relevant. One of the best posts I've seen about good ways to build sites is Brett's "how to build a site in 12 months" post.
