I came across a rather interesting idea (via Intial Charge):

I added a widget to every page here that lets anyone in the world immediately send me a notification. Type a message, hit send, and it’ll pop up on my phone, watch, and computer near instantly.

Is this a good idea? No. But it’s a funny idea, and that’s all that counts these days. Scroll to the bottom of this page if you want to give it a try.

I liked the idea so much, I decided to implement it here on this blog! So at the bottom of a post (while I still think it's a good idea), you'll be able to send a message directly to my phone.

For those interested, it uses ntfy.sh to send the messages.
