I know enough to make me dangerous. I know better than to be dangerous. I chose to protect, rather than to attack. 🅅

How far can a toot travel in the fediverse?

I chatted recently with someone who complained that the fediverse lacked "reach".

So I'm curious: if you are up for it, could you please reply to this toot (which started life on single user instance on a tiny computer in a garage in the United Kingdom) saying which country you are in?

Edit: 12 hours, 74 countries: https://neilzone.co.uk/2025/04/a-toot-travelled-to-fediverse-users-in-53-countries-in-12-hours/

#CyberHygiene is an important topic, now more than ever, and even more so as time goes on, especially in the new-world of #AI. So, let's have a quick chat!

I talk about this in my #AwarenessTrainings that I put together for my company. People sometimes have the mistaken notion that they aren't targets for bad actors because they aren't famous and don't have a high net worth, or don't have a high-profile job. But that's simply not the case today. Anyone with any online presence is a potential target to attackers. That means everyone needs to know their cyber hygiene. So what does that look like?

Basic cyber hygiene is essential and easy. Steps include (extra details below):
➡️ Be more stringent about the info you share online 📅
➡️ Review and adjust #privacy settings 🔒
➡️ Use strong and unique #passwords 🗝️
➡️ Enable two-factor #authentication 🗝️
➡️ #Monitor online presence 👀
➡️ Learn about data brokers ⬅️
➡️ Secure all devices 🔐
➡️ Be skeptical of unsolicited requests 😯
➡️ Regularly audit third-party apps with access to your accounts ❗
➡️ Monitor credit reports 💰
➡️ Separate personal and professional identities 👬

I go into A LOT more detail about each point in my recent blog post (TL;DR for  lol). Check it out here, and let me know your thoughts or questions!

We should reopen and #evangelize #libraries, and I think everyone should spend a few hours per week just finding any book on any topic and reading it cover to cover. There's still something to be said about holding a #book, especially an old one, in your hands. Flipping the pages. Absorbing its scent. Not saying you can't get the same experience digitally, but many people don't use their digital devices for true #learning and #cognitive growth. Apps and games aren't the same.

It's how I grew up and fed my deepest #addiction - #learning - spending hours in the library and just reading. The Internet barely existed. That's true knowledge. Ever learning. Ever #craving more. And I believe knowledge is true power.

I used to enjoy #deep, highly #nerdy, and rather #philosophical #conversations with many of my #peers and family members. I see that number of people who can "keep up", as it were, dwindling quite fast. Then I scroll through the little corners of the #Internets I do have active, and it astounds me how far people have #fallen, especially the younger generations. So #smart in so many ways - yet so mind #numbed in so much more.
