Arch-ive blog for Houston architecture

http://arch-ive.org/archive/about/ An excellent adaptation of the blog format as an archive of architectural images and news of older structures and for preservation advocacy. Self-description:  "Mission Statement: To photographically document and archive buildings and sites in Houston and surrounding areas, promote activism for present and future preservation of local architecture, and to increase awareness of Houston's architectural history. How/why/what? This site was created as a repository for mainly architectural photos...." Provides for several grouping options, e.g., architect, date, news, oddities, status, type, and zip code. Has a good list of related websites.
