I too stripped away my online presence a few years ago. I even went ahead further and deleted all my accounts I don't use, aren't privacy-oriented, etc. I now have a spreadsheet of the very few accounts I have for specific products and services. To that extent, I rarely sign up for anything new these days and or use a lot of applications and services.

I also say nay to having an online presence. I prefer silent, out-of-sight, deep work. On the other hand, I do support having a blog to journal and or log about anything you'd like, public or private. If public, I suggest to not use your real name, etc, but an unusual name like a 8-bit binary number.

Not having an online presence is free-ing. Having an online presence feels like you're a brand and are subjugated to update. Cal Newport might have talked about something along these above things in his latest book, "Digital Minimalism".
