My weblog ain't nothing special and gets basically no hits (as befits its basically-no-new-posts), but it's 16 years [1] old and still all there (albeit with the first couple of years somewhat scrambled from some importing across systems; just never taken the time to sort it out), and all mine. Has your content lasted 16 years?
The only thing about his piece that surprised me was referring to putting something on wordpress.com as a happy ending, since it seems like the same basic problem.
[1]: Jeepers, my blog can get a learner's permit. When, metaphorically, did that happen?
