RSS

RDF Site summary or Really Simple Syndication is a feed that enables applications
to subsribe into websites and query if they have new content.

This is an easy way to “subscribe” without really subscribing!

My RSS Link Feed:
RSS LINK
If you press this link while having an active extension for reading RSS,
Like the one below it will let you subsribe to the website feed status.

RSS Reader

I use this feed reader for chrome:

There are many readers available and if you are a programmer you can try to build your own!
