Yiziphi ezinye izibonelo zanamuhla zezinkampani eziye zasebenzisa amandla omphumela wenethiwekhi?
Context:Ezomnotho, umphumela wenethiwekhi (obizwa nangokuthi i-network externality noma i-demand-side economies of scale) yisimo lapho inani noma usizo umsebenzisi aluthola entweni noma kwinsizakalo kuncike enanini labasebenzisi bemikhiqizo ehambisanayo. Imiphumela yenethiwekhi ivame ukuba mihle, okuholela ekutheni umsebenzisi othile athole inani elengeziwe kumkhiqizo njengoba abasebenzisi abaningi bejoyina inethiwekhi efanayo. Ukwamukelwa komkhiqizo ngumsebenzisi owengeziwe kungahlukaniswa ngemiphumela emibili: ukwanda kwenani kubo bonke abanye abasebenzisi ("umphumela ophelele") kanye nokukhulisa isisusa sabanye abangasebenzisi sokusebenzisa umkhiqizo ("umphumela ophansi").  Imiphumela yenethiwekhi ingaba ngokuqondile noma ngokungaqondile. Imiphumela eqondile yenethiwekhi ivela lapho usizo lomsebenzisi othile lukhula ngenani labanye abasebenzisi bomkhiqizo noma ubuchwepheshe obufanayo, okusho ukuthi ukwamukelwa komkhiqizo ngabasebenzisi abahlukene kuyahambisana. Lo mphumela uhlukile emiphumeleni ehlobene nentengo, efana nenzuzo kubasebenzisi abakhona ngenxa yokwehla kwentengo njengoba abasebenzisi abaningi bejoyina. Imiphumela eqondile yenethiwekhi ingabonakala ngezinsizakalo zokuxhumana nabantu, kufaka phakathi i-Twitter, i-Facebook, i-Airbnb, i-Uber, ne-LinkedIn; amadivayisi ezokuxhumana afana nocingo; kanye nezinsizakalo zokuthumela imiyalezo ngokushesha njenge-MSN, i-AIM noma i-QQ. Imiphumela yenethiwekhi engaqondile (noma ehlanganisa amaqembu) ivela lapho "kunamaqembu amakhasimende okungenani amabili ahlukene axhomeke komunye nomunye, futhi inzuzo yeqembu okungenani elilodwa ikhula njengoba amanye amaqembu ekhula". Ngokwesibonelo, i-hardware ingase ibe yigugu ngokwengeziwe kubathengi ngokukhula kwesofthiwe ehambisanayo.  Imiphumela yenethiwekhi ivame ukuphathwa ngokungeyikho njengokusebenzisa imali ngesilinganiso, okuchaza ukwehla kwezindleko zokukhiqiza ezijwayelekile maqondana nomthamo ophelele wamayunithi akhiqizwayo. Umnotho wesilinganiso uyisimo esivamile ezimbonini zendabuko ezinjengokukhiqiza, kuyilapho imiphumela yenethiwekhi ivame kakhulu ezimbonini zomnotho omusha, ikakhulukazi ubuchwepheshe bolwazi nokuxhumana. Imiphumela yenethiwekhi iyisici esiphikisayo sokufunwa kwemali engenayo, njengoba isebenza ngokwandisa ukuzimisela kwamakhasimende ukukhokha imali efanelekile kunokwehlisa izindleko zabahlinzeki.  Lapho ifinyelela isisindo esibucayi, umphumela we-bandwagon ungavela. Njengoba inethiwekhi iqhubeka iba yigugu ngokwengeziwe ngomuntu ngamunye omusha owamukelayo, abantu abaningi bayakhuthazwa ukuba bamukele, okuphumela ekubeni kube nesixhumanisi esihle. Ukulinganisela okuningi kanye nokugunyazwa kwemakethe kuyizinto ezimbili ezingase zivele ezimakethe ezibonisa imiphumela yenethiwekhi. Ukulindela kwabathengi kuyisihluthulelo sokunquma ukuthi iziphi iziphetho ezizovela.
Izibonelo zezinkampani zanamuhla eziye zasebenzisa amandla emiphumela yenethiwekhi zihlanganisa izinsizakalo zokuxhumana nabantu ezinjenge: TikTok, Youtube, Twitter, Instagram, Facebook, Airbnb, Uber, kanye ne-LinkedIn.
