Dan Lyon's thoughts on a current tech bubble...
if you characterize a bubble as something that can only take place in
public markets, fine, there is no bubble. If you characterize it more
broadly as a phenomenon in which companies with no profits and
unworkable business models are able to raise millions of dollars in
venture money, and then when each unworkable company leads to six or
eight copycat companies that also get funding, and when a company like
Facebook is valued at $15 billion — um, in the broader sense of the
term bubble, I’d say that would be one.
