I often wish it were possible, via RSS or some other online mechanism, to catch up on some content you discover online long after it starts. It's overwhelming to look at a website - a blog or a web comic - with several years of history and feeling like you'll never get to catch up. There aren't any tools for dealing with that, you know? All you can do is go to the beginning and click through each page manually, until you get to the point where you are caught up and can finally subscribe. I did that with Starslip, when I finally discovered it, and then it had stopped forever by the time I caught up.
It works well enough if it's a normal website, but if it's on Facebook, like Daniel H. Wilson's Amped prequel blog of fictional character Samantha Blex, it is much, much worse. The only thing you can do is scroll up and down the page, visually scanning to make sure you're looking at the right entry in sequence and clicking to expand each one. That's probably more a problem with Facebook's Timeline, though.

PS - I am looking forward to reading Amped.
PPS - But that's getting further off topic.
