All you can do here is look at posts and photos.
When you're looking at a post or a photo the orange link in the upper-left corner navigates to a newer item whereas the link in the upper-right goes to an older item.
Photos can be displayed as individual photos or in 3x3 sets. Clicking on a photo usually jumps between the displays.
In the 3x3 photo set the newest photo is in the upper left corner, the oldest in the bottom-right corner. Navigation is via set number.
Photos in a 3x3 set can be filtered by location, rating (0-4), and/or date added. Whatever filter you choose is also applied to the single photo/random photo display.
Posts have un-obvious click points:
Click the date (right of the title) and out will pop the url of that post.
Click a keyword (right of the date) to find posts with that keyword.
Click the under-the-photo caption to see location, date, and exif. Once there click the location to filter photos by location. In fact, any time you see location it's probably a link.
Click on the photo itself to display the photo in context with other photos, in a 3x3 grid.
Photos have un-obvious click points:
Click the location to filter photos by location.
Click the post name (if there is one) to show that post.
