RSS
To learn about RSS feeds, read this post.
This site has multiple RSS feeds:
The main feed contains all posts on this site. This is the front page, plus the RePost category, which includes content created elsewhere that I find interesting and highlight here.
The front page feed contains all posts written originally for this site, plus anything not original that gets upgraded out of RePost and onto the front page.
The comments feed tracks all comments made on any post. If you want to track comments on an individual post, see the comments box at the bottom for RSS or email options.
The photo feed gets updated whenever new albums or photos are added to the photo part of this site.
I don’t use Twitter much but you can subscribe to my Twitter feed too.
There is a Geo RSS of the map of my upcoming trip to Antarctica.
