Articles written by a single editor have a higher probability of needing attention than those which have received contributions from several editors. So, we generate a list of articles that have been written by an inexperienced editor and have not yet received any collaboration.
Some of the articles are good, but others need to be fixed or flagged appropriately, so that the topic experts can enhance them. When reviewing an article, the underlying idea is: Fix what you can fix and tag the rest, so that more experienced editors can find and fix them.
Helping is easy, fast and even entertaining, if you are curious. First open the Articles list in a new window, and begin reviewing the articles. When you're done, delete the article(s) from the articles list. Feedback is always welcome on the talk page.
