AIW meaning in Community ?

Deletionism and inclusionism are opposing philosophies that largely developed within the community of editors of the online encyclopedia Wikipedia. The terms reflect differing opinions on the appropriate scope of the encyclopedia and corresponding tendencies either to delete or to include a given encyclopedia article.

"Deletionists" are proponents of selective coverage and removal of articles seen as poorly defended. Deletionist viewpoints are commonly motivated by a desire that Wikipedia be focused on and cover significant topics – along with the desire to place a firm cap upon proliferation of promotional use (seen as abuse of the website), trivia, and articles which are, in their opinion, of no general interest, lack suitable source material for high-quality coverage, or are too short or otherwise unacceptably poor in quality.

"Inclusionists" are proponents of broad retention, including retention of "harmless" articles and articles otherwise deemed substandard to allow for future improvement. Inclusionist viewpoints are commonly motivated by a desire to keep Wikipedia broad in coverage with a much lower entry barrier for topics covered – along with the belief that it is impossible to tell what knowledge might be "useful" or productive, that content often starts poor and is improved if time is allowed, that there is effectively no incremental cost of coverage, that arbitrary lines in the sand are unhelpful and may prove divisive, and that goodwill requires avoiding arbitrary deletion of others' work. Some extend this to include allowing a wider range of sources such as notable blogs and other websites.

To the extent that an official stance existed as of 2010, it was that "There is no practical limit to the number of topics it can cover" but "there is an important distinction between what can be done, and what should be done", the latter being the subject of the policy "What Wikipedia is not". The policy concludes "Consequently, this policy is not a free pass for inclusion".
