Fortune reported more tech optimism today. In addition, in a remarkably quick turnaround, the VCs now seem starved for deal flow. ("What ye shall sow, so ye shall reap"). In the last few weeks a stack of 'social networking' companies - Friendster, LinkedIn, Tribe - got funded at higher than recent A round valuations. More significantly, they were chased by VCs wishing to get in on the action. Haven't seen that since late 1999.
