+                </h3>
+                <p>
+                    Folksonomy is a system of classification that is created by
+                    individual people, rather than by professionals (who
+                    sometimes refer themselves as experts) such as archivers or
+                    librarians. It is a fashion for people to collaboratively
+                    tag and categorize information, often using keywords or
+                    labels.
+                </p>
+                <h4>
+                    Characteristics
+                </h4>
+                <p>
+                    Among the characteristics of folksonomy are: independency,
+                    collaborativeness, and being dynamic;
+                </p>
+                <p>
+                    Tags are self-generated by individual people, not by a
+                    centralized authority;
+                </p>
+                <p>
+                    Tags can be added by multiple people to the same item,
+                    and thereby they create a collective understanding;
+                </p>
+                <p>
+                    Tags can be added, removed, and updated over time,
+                    reflecting evolving usage, accuracy and interests;
+                </p>
+                <p>
+                    There is no single source of truth or control over the
+                    tagging process.
+                </p>
+                <h4>
+                    Benefits
+                </h4>
+                <p>
+                    Because people can easily find relevant content by searching
+                    for specific tags; and shared tagging promotes collective
+                    understanding and knowledge creation; and people feel more
+                    involved and empowered by contributing their own insights.
+                </p>
+                <p>
+                    The benefits of folksonomies spans from improved
+                    discoverability of contents to enhanced collaboration and
+                    increased engagement of people by contributing and
+                    benefiting to the overhaul system.
+                </p>
+                <p>
+                    It was written in Adam Mathes' recent paper on folksonomies that:
+                </p>
+                <p class="quote">
+                    “There is a fundamental difference in the activities of
+                    browsing to find interesting content, as opposed to direct
+                    searching to find relevant documents in a query. It is
+                    similar to the difference between exploring a problem space
+                    to formulate questions, as opposed to actually looking for
+                    answers to specifically formulated questions. Information
+                    seeking behavior varies based on context.”
+                </p>
+                <h4>
+                    Conclusion
+                </h4>
+                <p>
+                    By practicing and engaging in folksonomy systems, people
+                    find many interesting resources that are related to their
+                    special and specific needs, that they could not have found
+                    using search engines. Blasta has some interesting advantages
+                    over search engines, and one of them is being folksonomy
+                    driven.
+                </p>
+                <p>
+                    The power of the people cannot be more evident than the
+                    awesome resource that is Wikipedia, albeit is has been
+                    gradually controlled by
+                    <a href="https://www.fivefilters.org/2023/glenn-greenwald-on-wikipedia-bias/">
+                    special interests</a>. Imagine what might happen if a search
+                    engine (e.g. YaCy) can be engineered by people!

+                    associations is just a lot easier than making a decision
