Portal:Category theory

 * – (View MfD)

Neglected portal. Clearly fails WP:POG. ToThAc (talk) 18:24, 9 September 2019 (UTC)
 * Six selected articles; a third are C-class, while the rest are B-class.
 * Only maintained by the creator for about five-thirds of a month. They last edited in April Fools' 2017, and I see no other evidence of adequate maintenance.
 * Pageviews are definitely low, making up a .2308% daily average of the parent article in the first half of 2019.
 * Delete - Not enough articles, not enough maintenance, not enough readers. The topic is only a "broad subject area" in the highly abstract sense that it can be used as a meta-theory to categorize any mathematical concept, or any concept that can be abstracted mathematically.  The subject does not have to do with Wikipedia categories, or with the epistemological categories of philosophers including Aristotle and Kant, but is a mathematical abstraction that does sort of encompass all of the above.  The portal has 12 daily pageviews in Jan-Jun2019, as opposed to 520 for the article (or 2.3%).  The portal has 10 subpages including biographies, of which 9 were originated in 2010 and one in 2011.  Most of them have had formatting improvements, and one had vandalism reverted.  The only substantive change was the addition of a date of death to a biography.  We need an article on the subject; we have an article.  Robert McClenon (talk) 22:44, 9 September 2019 (UTC)
 * Delete per the nom and Robert M. This portal has been abandoned for over a decade, save a few minor one-off updates by passing editors, and has very low readership, which are both clear fails of WP:POG. Since late 2006, the lead of WP:POG has said "Do not expect other editors to maintain a portal you create" ... and this one has not been maintained by Cenarium, who last updated it in April 2008, two months after creation, and last edited portal space April 1 2011 and Wikipedia on April 1 2017. I oppose re-creation, as a decade of hard evidence shows Category theory is not a broad enough topic to attract readers or maintainers. Newshunter12 (talk) 03:07, 10 September 2019 (UTC)
 * Note to closing admin. I don't want in any way to prejudge the outcome ... but if you close this discussion as delete, please can you not remove the backlinks?  I have an AWB setup which allows me to easily replace them with links to the next most specific portal(s) (in this case Portal:Mathematics), without creating duplicate entries. --  Brown HairedGirl  (talk) • (contribs) 21:53, 10 September 2019 (UTC)
 * Related discussions. This is one of three abandoned portals created by which are currently the subject of MFD nominations.  The other discussions are at MFD:Portal:Set theory and MFD:Portal:Discrete mathematics. --  Brown HairedGirl  (talk) • (contribs) 08:15, 12 September 2019 (UTC)
 * Delete, and oppose re-creation. Low readership + poor maintenance = clear fail of the WP:POG requirement that portals should be about "broad subject areas, which are likely to attract large numbers of interested readers and portal maintainers".
 * WP:POG also guides that "the portal should be associated with a WikiProject (or have editors with sufficient interest) to help ensure a supply of new material for the portal and maintain the portal". In this case there is no WP:WikiProject Category theory, and the broader WP:WikiProject Mathematics doesn't seem interested. Relevant discussions are:  Feb 2019 lament about the flood of portalspam, with subsequent discussion, plus an April 2019 question by Legacypac asking "Which of these approx 30 Portals does the math project provide support to or are you interested in managing?". Legacypac's plea brought only one response, and no offers of maintenance. --  Brown HairedGirl  (talk) • (contribs) 20:37, 12 September 2019 (UTC)
