Mike Rundle tiene algunas opiniones bastante acertadas acerca de WordPress y Movable Type. En general explica perfectamente la razón por la cual decidí usar WP sobre MT para Hipertextual. El último párrafo da un buen resumen de todo su post.
It seems to me that unless Six Apart really gets its act together and revitalizes the entire Movable Type application, codebase, and community, new bloggers will no longer use MT but will use WordPress instead, a change that's already happening. WP's active development and range of free blog themes to choose from are extremely inviting to new bloggers. I know that a very nice WP admin theme is currently brewing so we'll have to see if it can live up to the standard that MT has set.
