The current dmoz Tip of the Fortnight
It is considered bad form to use slang or abbreviations like “info”, “pics”, “etc” and “bio”. Using the full form of the word is not only more professional but is also easier for our users, whose native language may not be English, to understand or translate.
A very good tip. Every writer should remember not to use slang and abbreviations, unless they are very well known by the general public. Some sites or publications may have a very narrow readership they can focus on. But, even those sites could have a glossary or some way to understand their abbreviations.
