Internet category is cycled
Hi, I found this structure: Is if OK, or should be fixed? ~ Нирваньчик ~ ⊤άλҟ 21:27, 26 November 2011 (UTC)
 * Computer networks -> Internet‎‎
 * Computer networks -> Internet‎‎ -> Computer networks by scale -> Wide area networks -> Internet‎‎
 * IMHO it's OK, because the is not a parent of itself. As shown by the category tree, the current structure is:
 * Computer networks -> Internet‎‎
 * Computer networks -> Computer networks by scale -> Wide area networks -> Internet‎‎
 * However, There is an old English proverb, "The Devil is in the details," meaning, among other things, that the specific provisions of a general plan may be controversial. &mdash; John Harvey, Wizened Web Wizard Wannabe , Talk to me! 17:34, 27 November 2011 (UTC)
 * Oops, looks like I confused the structure. Sorry for disturbing for nothing. But now I see that Internet is twice in category Computer networks. Is it normal for categories or mistake or kind of exception? I used to the fact that guys usually remove grand-grand-parent category (here Computer networks) from a category (here Internet) if parent of the category is already child/descendant of that grand-grand-parent (or grand-parent). ~ Нирваньчик ~ ⊤άλҟ 23:34, 27 November 2011 (UTC)
 * As a practical matter, I can see the value of having it both places even though it is logically inconsistent. Since I don't know of any rules, I am planting my feet firmly on both sides of this fence. However, we may get some guidance from Wikipedia_talk:WikiProject_Categories. &mdash; John Harvey, Wizened Web Wizard Wannabe , Talk to me! 14:12, 28 November 2011 (UTC)
 * The category "tree" isn't a tree at all, it's a directed graph. It is common for a category to appear in multiple places in the "tree". It's also not particularly uncommon to find cycles; for example, Category:Black Sea is a subcategory of Category:Landforms of Romania, which is a subcategory of Category:Geography of Romania, which is a subcategory of Category:Romania, which is a subcategory of Category:Black Sea countries, which is a subcategory of Category:Black Sea. There's nothing necessarily wrong with that. Anomie⚔ 17:57, 28 November 2011 (UTC)
 * The current arrangement makes fine sense to me:
 * Computer networks -> Internet‎‎
 * Computer networks -> Computer networks by scale -> Wide area networks -> Internet‎‎

 * The category "tree" isn't a tree at all, it's a directed graph. - This explains everything. Ok then. Reason and sence are determinative here. Good. ~ Нирваньчик ~ ⊤άλҟ 11:05, 29 November 2011 (UTC)
