> It was already a top visited site when its development team consisted of a single person, Brion Vibber. There have been very little significant development since then […]. The second member of the development team was hired in 2006 [0]. In these ~14 years, quite a few things happened. Three projects joined the Wikimedia galaxy: Wikiversity in 2006, Wikivoyage adopted in 2012, and frickin’ Wikidata [1] in 2012 − which has deeply reshaped many aspects of the other projects, particularly Wikipedias and Commons. On the multimedia side of things, we got InstantCommons in 2008 [3], thumbnailing infrastructure changes in 2013, various file format support (TIFF in 2010, FLAC and WAV in 2013, WebM, 3D formats in 2018 [4]) new upload wizard in 2011 [5]. The Graph extension [6] and Wikimedia Maps [7] in 2015. Structured Data on Commons in 2019 [8]. New default skin (Vector) in 2010 [9]. Unified login in 2008 [10]. 2013 brought OAuth [11], Echo notifications [12], Lua scripting [13], VisualEditor [14]. iOS and Android apps [15]. The Wikimedia Cloud Services starting 2012 [2]. (And in terms of size: article count went from ~5M to ~50M [16] ; Commons went from 1M files to 50M files [17]) And that’s just what I’m putting together in a few minutes (Besides my own memory, I’m indebted to [18], a curated timeline up until 2013). Of course, these may or may not justify the staff size in your book ; but I’d say discounting all of that (and the rest) as “very little significant development” is a bit pushing it. :-) (And fairly sure that “you’d probably notice” if Wikipedia was still using good’old Monobook skin ;-þ).
