I had made the mistake of writing posts straight into the Wordpress site, and its security at the time was not up to much, so I found. It'd been problematic to upload posts from Word docs so I just started writing straight into the blog site, and at that time there was no obvious (to me, anyway) way of backing up the site.
I later received an email from someone looking for some of the old posts. He kindly said that it was some of the best writing on photography he'd seen online, which was a very flattering comment to receive.
I have just used The Wayback Machine to relocate much of the written content of the Photography matters blog, although the photos are in most cases not preserved. If you want to read the old posts, they all under the Historic category.
I am not going to repost the articles relating to the NZCP dissolution, though; that is all dead and buried. If you really want to research it, go to The Wayback Machine, search under PhotographyMatters.com, and look at the 2008 captures. All the best.
