Twitter After refusing to be bought by Facebook for 500 million dollars (although part of this payment is in shares), Twitter returns to the world of Risk Capital and prepares to raise another 20 million to the previous 20 million already raised, being valued at 250 million dollars.

O Scobleizer made an interesting parallelism: if they are part of the 6 million Twitter users (number that grows daily), assuming that the only Twitter asset are users, each user is worth 42 dollars (ok, this is not purchase cost).

When I look at customers BySide, the purchase cost of its customers varies between €30 and €150€ (communication and sales commissions). For Twitter... not bad!

With a giant and participatory community all Twitter lacks is a small detail: a business model.

As a user who thinks Twitter offers something very close to a public service, I worry that a new “round” of investment will slow and lazy the need for Twitter to create a sustained business model...
