Sometimes blog has a RSS in header

[AbhiAgarwal]

<link id="feedLink" rel="alternate" type="application/rss+xml" title="RSS" href="https://medium.com/feed/@abhiagarwal">

It gives you the feedLink. If someone gives us a blog or adds a blog to the contact we can try and visit it and get the feedLink. It's an optimization, but will leave it here!

Kinda hard depending on site:

  <section id="feed_link">
  <a href="http://abhiagarwal.com/posts.atom">
    <span class="feed-icon"></span>
  </a>
</section>

<link rel="alternate" type="application/rss+xml" title="La Rose Quotidien &raquo; Feed" href="http://larosequotidien.com/feed/" />

We can start off by doing it only for wordpress sites then go from there.
