The so-called social web explosion of web2.0 is nothing more than infrastructure. myspaces, diggs, youtubes – all make it easy for you to create a profile, add your own content, and then link to others. The wild woolly world of the free internet is just too chaotic and formless to act as a lone gun.
You need your mates online, and you need to be able to connect to them easily. That’s web2.0.
1) flickr – upload your photos, connect to others
2) youtube – upload videos, connect to others
3) myspace – upload your life – connect to others
4) delicious – save your bookmarks, connect to others
These companies succeeded because they built fast, reliable infrastructure, and let their users do the rest.
