List posts are popular because:just see what is the most pop bookmark in delicious.com:
so facts tell you the turth,why we should make list posts:
1. Lists are to the point—online readers are notoriously lazy and tend to
scan content rather than read it word for word. A list helps
communicate a number of points quickly and easily, and helps readers
know if a post contains information of interest to them that they should
actually read more of.
2. Lists keep posts are simple—there is something about a list that keeps
you as a blogger from rambling. Each point has a start and end,
whereas with an essay style of writing, points often bleed into one
3. Lists look neat—I don’t know about you but when I surf onto a site
that’s full of messily formatted text I tend to keep my stay short. Lists,
on the other hand, can be visually pleasing and more likely to stimulate
4. Lists can be comprehensive—while some might argue that lists dumb
down ideas and concepts, when written well they are actually just as
comprehensive as any other style of writing.
5. Lists are persuasive—if you want to mount a case quickly, presenting
numerous arguments in a list can be quite convincing. Again, it’s about
identifiable points that together go to forming a convincing argument.
6. Lists can add to the ease of writing—I like writing in lists because
they break down my thoughts into bite-sized pieces, which is good for
my readers and me as a writer, as I consider how to express myself.
7. Lists go viral—lists can start epidemics of ideas. For the above
reasons and more, bloggers and social media aficionados seem to love
sharing lists and, as a result, they spread quickly throughout the web
8. Lists break down the complicated—one reason I find list posts to be
powerful is that they can break down complex ideas or tasks. I know
on my photography blog that many of our Photoshop tutorials work
best when our authors present their instructions as steps; that way, a
procedure that can at first seem overwhelming becomes accessible as a
list of bite-sized tasks.
Warning: limit your list posts. They can be incredibly powerful but readers
can become frustrated with them if that is all you do.
