I'd been toying with the idea of a full-fledged photoblog for a while, but kept putting it off because I wasn't sure I wanted to run another site completely separate from this one. After weighing all the options I've decided to continue posting the photos here as regular weblog entries and will likely open up comments on them in the future (unlike my other posts), in addition to those I already allow on Flickr.
I've also decided to stop advertising my Flickr RSS feed and will now handle that in-house. The new feed for my photos will simply contain those weblog entries that are in the "photos" category. If you are subscribed to the main weblog feed you don't need to change anything (the pictures will still be included in that feed), but if you only want the posts with pictures, then subscribe to the photos feed.
