1.7 Where can I search for it?
1.7.4. Discussion groups and distribution lists
A discussion group is a virtual community of users who are interested in a given topic.
In some cases it may be useful to perform a search in the contributions provided in these expert communities. Even if the number of users is not usually large, they have the advantage of possessing a broad, specialized knowledge on the subject we are interested in.
For instance, in websites such as https://stackexchange.com we may find questions and answers (and ask questions ourselves) on a wide variety of topics. The quality of the information depends on the users who belong to the discussion groups, and for this reason some of the initiatives have been undermined in terms of the quality of results.
