Tobias Luekte has set up a Trac site for his Typo weblog engine. Typo has a slew of neat features including:
- XML-RPC backend implementing the metaweblog api. MarsEdit and other desktop clients work great.
- Comments
- Textile by way of RedCloth
- fulltext search
- RSS2 and Atom export
- CommentRSS export
- Some use of caching and sweepers
So whether you’d like to run it or not, you’ll probably do well by having a look at the source.
