I don't, if only because a constantly mutating title makes searching harder. Interested readers should be able to use the site's search function pretty quickly, without having to wade needlessly through the index.
You can go to the end of your current thread. Some where near there will be a link to the next thread.
You can change the search function to "Users" instead of "Keywords" and then search for Mariner. I was also irritated with the title changes until it occurred to me to search for Mariner instead of the most recent thread title.
