Cu toate ca au trecut multi ani de la aparitia WWW-ului, notiunile de Web 1.0, 2.0 si 3.0 au aparut mult dupa aparitia efectiva a lor. De fapt, ne-am dat seama de Web 1.0 abia dupa ce si-a facut intrarea Web 2.0, prin contrast cu acesta. Pana si in ziua de azi multa lume nu intelege exact aceste notiuni, sau nu le vede rostul, de aceea voi incerca sa fac o scurta prezentare a acestora.

Web 1.0 este prima implementare a web-ului, pe care o putem considera “read-only web”. Astfel, in web-ul initial puteam sa cautam informatie si sa o citim. De fapt, cam acesta era si scopul proprietarilor: website-ul exista pentru a face informatia disponibila oricui si oricand. Vizitatorul nu se putea implica in crearea continutului Web.

Web 2.0 permite crearea de bloguri, wikiuri, upload de continut media (youtube.com), si site-uri de retele sociale (MySpace.com, hi5.com). Aici, utilizatorii participa activ la punerea la dispozitie si raspandirea informatiilor prin intermediul web-ului.

Cautand o comparatie cat mai usor de inteles intre cele doua, am gasit urmatoarele randuri care explica cel mai bine diferentele intre Web 1.0 si Web 2.0:

• Web 1.0 was about reading, Web 2.0 is about writing
• Web 1.0 was about companies, Web 2.0 is about communities
• Web 1.0 was about client-server, Web 2.0 is about peer to peer
• Web 1.0 was about HTML, Web 2.0 is about XML
• Web 1.0 was about home pages, Web 2.0 is about blogs
• Web 1.0 was about portals, Web 2.0 is about RSS
• Web 1.0 was about taxonomy, Web 2.0 is about tags
• Web 1.0 was about wires, Web 2.0 is about wireless
• Web 1.0 was about owning, Web 2.0 is about sharing
• Web 1.0 was about IPOs, Web 2.0 is about trade sales
• Web 1.0 was about Netscape, Web 2.0 is about Google
• Web 1.0 was about web forms, Web 2.0 is about web applications
• Web 1.0 was about screen scraping, Web 2.0 is about APIs
• Web 1.0 was about dialup, Web 2.0 is about broadband
• Web 1.0 was about hardware costs, Web 2.0 is about bandwidth costs
