Ask HN: Well designed product blogs?

Doing a bit of a prep for a project and now looking for examples of well designed product blogs, with an emphasis on designed. Something tasteful, polished and with character. Something that would make one want to go straight to the main site and see what it is they have designed as a product.

http://www.panic.com/blog - the best example I can think of

http://culturedcode.com/things/blog - the second best example

http://taptaptap.com/blog - yet another example, though it is IMO a bit overdone

From the top of your head - any other examples? Feel free to plug your own stuff if it stands up to a critique :)
