John Battelle pointed me to this piece by Seth Goldstein, who in previous life ran an Internet consultancy and then a research firm. (… explains, the length of the piece….) Hate to say this, but to paraphrase John Doerr, seldom has been so much written about so little. But since I toil for you, so here it is, the only line worth remembering. Every new web application or mash-up from HousingMaps to Backpack to Del.icio.us is simply a better enabler of some existing user behavior. That is the essence of Web 2.0.
