What's your use case?
I would like to be able to follow your blog/news and be warned when a new article/info is published.
What's your proposed solution?
Adding an RSS/Atom feed to your blog would be great.
According to your blog's error page, you are using GitHub Pages to publish your blog:
https://orangedatamining.com/feed.xml
According to this article, it is possible to add an RSS feed to such a page:

Are there any alternative solutions?
The twitter feed is also interesting but not free (as in speech) and not as simple.
Also content is not the same (as a side note it would be great to be able to access your news without creating twitter account)
