The semantic blog. I've long dreamed of using RSS to produce and consume XML content. We're so close. RSS content is HTML, which is almost XHTML, a gap that HTML Tidy can close. In current practice, the meat of an RSS item appears in the <description> tag, either as an HTML-escaped (aka entity-encoded) string or as a CDATA element. As has been often observed, it'd be really cool to have the option to use XHTML as well. Then I could write blog items in which the <pre> tag, or perhaps a class="codeFragment" attribute, marks regions for precise search. You or I could aggregate those items into personal XPath-aware databases in order to do those searches locally (perhaps even offline), and public aggregators could offer the same capability over the Web.
