If you're an article writer, I am sure that your main goal is to get people to pay attention to your copies. One of the steps that you need to take to make this happen is to choose topics that they would love to read about. Are you going to discuss those current ones or those that are considered timeless?
Writing current topics can surely benefit you but only for a short period of time. For example, you can write an article about Kanye West's behavior during the VMA's and you can be assured that you'll get enormous traffic. Why? It's because people from across the globe are now going crazy about this issue. In fact, Kanye's video in YouTube already got millions of hits. But what happens after a month or so? Do you think people will still remember Kanye's antics? I really don't think so.
On the other hand, writing timeless topics can offer you with long lasting results. For example, you can write anything about SEO and your topics will still be considered important five years from now as it will still be the fastest way to the hearts of the search engines.
Conclusion: I recommend that you write both current events and timeless topics as much as you can. Both can give you the kind of attention you need. Just make sure though that all the topics that you write about are closely relevant to the theme of your website so you'll be able to attract high quality traffic or those people who are most likely to get interested on what you sell.
