From the Guide to Surviving RO:
5. Posting articles When posting an article, DO NOT post the entire article. The proper way of posting an article is to include the first and second paragraph and then post a link to the source of the story.
Depending on the length of the paragraphs and the length of the article I sometimes post more or less than the entire first and second paragraphs. If you’ve seen many articles I’ve posted you’ll have noticed that I use the same format (title hyperlinked, author, source, time/date, quote). It’s the format required at another discussion site I frequent.
Underlying RO’s and that other site’s rules is that discussion sites have been sued over entire articles being systematically posted over extended time periods, and have lost. Until recently there was a company whose entire business model was extorting $$ from bloggers who posted articles or large quotes from articles to which the company had bought the rights. The courts smacked this company down, and it is near or in bankruptcy, but being careful is necessary.
Please don’t feel like I unloaded a ton of bricks on you … just letting you know RO’s rule isn’t arbitrary.
