Thanks for the kudos cooperadymas.<p>We take a snapshot every time you visit the page. We don&#x27;t version the page yet. Do you have a specific use case for a feature like that?<p>There&#x27;s a very strong correlation between time spent and usefulness of the article. We index all articles, even the ones you spend less time on, so when you search, a few page scrolls get you to the link you need. That said, time spent is a heuristic, its useful in a lot of cases, but not all, we&#x27;ll have to see.<p>&quot;Proprietary algorithms&quot;, we have a patent pending on how we sort and filter data<p>We&#x27;ll think of a catchphrase around &quot;&quot;Imagine never having to re-google what you had googled before&quot;<p>Hope you enjoy using the extension.
