I have the same problem with my blog. It only finds stuff from
several months ago. Certain keywords even have my blog appear in the
"Related Blogs" list above the results, but new posts still won't come
up. Sometimes a new post will appear for a few hours after it was
created, then it will disappear again. It cannot be found in either
relevancy or date rankings.
Of course, maybe I just can't find it among all the freaking SPAM.
Earlier tonight it was 5 pages of results, all of which were fake DVD
review SPLOGs, before I found a legit blog post.
I wish I had an answer, but at least we both know it's not just
ourselves this happens to.
