Using a bibliography?

I am excited to use the bibliography functionality, but I must be missing something about how it works.

I made files out of the example Post and Bibliography from the example page.

But the post that ends up on my blog page just looks like the raw text - it hasn't been parsed, i.e. it looks like:

Blah blah [see @item1, pp. 33-35; also @item2, chap. 1].

Blah blah [@item1, pp. 33-35, 38-39 and passim].

Blah blah [@item1; @item2].

I put the Bibliography.bib file in the same folder as the text file containing the Post. What am I missing?
