Taken from the sites FAQ
2. Who can write here? - Anyone. We don't edit for size or content. The only restriction is you have to write about science. We don't get into defining what is science and what isn't science. It's self-evident in most cases. Poems about your cat, for example, are not science but an article on information theory using cats is. If you look at the categories and can't find where your article would fit, tell us we need a new category.
3. Some writers will already have an audience. How do I get one? - Each new article that is published will appear on the front page for a short while. It will also appear on the Science Category pages. Well-written articles become popular and they will remain in the front of the main page or category pages. Just write good content and people will start reading you.
4. Do you censor any content? - No, the only content moderation of any kind will occur if someone violates the Terms of Use. We don't allow advertising or teasers that are links to websites. We do allow linking to articles provided you obey copyright restrictions as spelled out in the Terms of Use. Authors have moderation ability over the comments in their columns. We recognize that spam and trolling occur and allow authors to prevent that.
I'm not too convinced of how reliable this sorce is.
