You get more attention by writing your own articles than just commenting on articles written by others. A well written article is regarded as more authoritative than brief comments, but keep in mind that people also expect a higher quality and accountability from you. We encourage the use of freedom of speech while keeping the decency in the way the article is written at a reasonable level. So, by following our guidelines you should expect us to publish your articles.
