There are many ways to view new content without going to the site:
RSS Feed - add it to your RSS reader.
Facebook - get notified on your favorite website.
Twitter - get notified on my favorite website.
Friendfeed - remember Friendfeed?
Podcast - Using text-to-speech technology, Odiogo.com transforms written posts into audio mp3s. I've been using this service for 4 or 5 years now.
Want to view old content?
Archives - on the right-hand side of the site is an Archive button (file cabinet icon), but I prefer using the Twitter page which lists all posts with links.
Best of Luggage Tuesdays - Taking the Twitter page as archives concept a little further, I've "starred" the best material, which can be found on the Twitter account's Favorites page.
Compilations - I've complied old material and posted it on Scribd. There are embedded below.
Want even more content?
Ebaumsworld - I've been blogging there.
Hanging With My Tweeps - Live weekly video podcast. I post them on Luggage Tuesdays.
Luggage Tuesmblrs - Official Tumblr site. Lots of stuff that wouldn't fit the official site.
Other Tumblr sites: Fuck Yeah Victoria Jackson, Aw Snap!, @Spiegelmania, Layover Comedy Night, The Bitter Show.
