Those who use TextMate together with John Gruber's Markdown to write for the web might be interested in HumaneText.service, which I discovered via Merlin Mann's 43 Folders site.
HumaneText is an easy-to-use OS X service that, by combining Markdown, SmartyPants, and html2text, enables you to convert Markdown-formatted text to XHTML and vice versa.
You can download HumaneText Service No. 4 here: http://gu.st/proj/HumaneText.service/
I've found that TextMate combined with Markdown is a marvellous web writing environment and HumaneText makes it nearly perfect.
