keep your stuff accessible
Earlier this week I read a well-done guide on how to use your phone less often (as he writes a blog post from his phone) that I thought was useful in some of the messaging. It was up at https://reddit.com/r/coolguides/ for less than a day before moderators took it down. I suspect it's because the guide lacked sources for some of the stated facts. The party also generated a lot of controversy in the comments, and the OP provided a downloadable PDF but put it on a website that requires a paid subscription (cancel anytime!) to access. So probably a myriad of reasons why it was taken down.
Regardless it underscores the notion that when you share stuff you've put a lot of care into online and want to share it, make sure that it's not at the mercy of moderators that can take it down at a moment's notice. Apart from myself several others were dismayed to find that it was no longer available - I was ready to download the images to save later.
Maybe one of those websites that archive reddit posts might be of use, but I need to find one of those first.
Anyway, the Internet might be written in ink but I think it's written with those erasable gel pens you can get nowadays.
(Those pens are pretty good actually, but not for longevity.)
